    8×10=80 4 leftover answer is 10 packages
    If you buy 10 packages there would be 4 leftover buns. I got my answer by doing 8×10 and got 80.

    (question) Your family is bringing hamburger buns to the family reunion. You need to bring enough for 76 hamburgers. The buns are sold in packages of eight. About how many packages should they buy?
    Explain your answer.(answer) (Eight times ten equals eighty. So the answer is ten.)

  3. Peter says:

    I got my answer by dividing 76 by 8 equals 9 with a remainder of 4. Even though I used the numbers the word problem provided me with, they don’t sell them in packages with a remainder, so I had to round my answer up to 10 packs.

    I would rather buy them at Cosco. This is because at Cosco it’s $15 for the buns, but at the supermarket it’s $20. I got the $20 by doing $2 x 10 equals 20. I got the $15 by doing $3.75 x 4. I only need 4 packages at Cosco because they sell them in packs of 20 instead of packs of 8. I counted by 20’s to get to the 80 buns I needed.

  4. Aiman says:

    I would do 8x_=76.It equals 56 and then get 20 more buns.Or get some extra more bags of buns.Thats how I got my answer.

    They have to buy about 12 packages of buns for the hamburgers at the family reunion.

    homework

    extra mile;I would rather get the 20 buns for $3.75 becuse there’s more in one packege and you are only wasting about $13.

  6. Christian says:

    76 divided by 8=9 R4
    The number of packages we should buy is about nine.

    Extra Mile
    9x$2.00=$18.00, super market
    $3.75×4=$15.00, cosco
    It would be cheaper at cosco.

  7. Anthony DeScalo says:

    8+8+8+8+8+8+8+8+8=72

    3.75 times 4 = 15.00

    $2+2+2+2+2+2+2+2+2= $18.00

    I found my answer by multiplying 8 and 9=72. But they need 76 so they need 1 more packege of buns. And it will be chepper at cosco because $3.75 times 4= 15.00. Also $2.00 times 9= 18.00. So it is deffintly chepper at cosco.

  8. SARA says:

    my answer was 9. I got it by 76/8 but there is a remainder the a remainder is 4 because 8×9=72 and thats the closes. Thats my answer.

  9. Zachary G. says:

    The answer is 10 packages.
    76 divided by 8 =9 with a remainder of 4. 8×9 is only 72 and you need 76 buns. You should buy and extra package and have 4buns left. over.

    Extra Mile:
    Costco is cheaper.

    Supermarket: $2.00 x 10 packages of 8 buns= $20.00
    Costco: 80 buns divided by 20 buns =4bags needed to get 80 buns. $3.75 x4bags=$15.00

  10. becky says:

    You should buy 10 packages and you get 80 buns in all. You get 4 buns left over.
    10 x 8 =80. 80-76=4.

  11. James Foley says:

    8*10=80
    9*8=72
    you should buy ten packages of 8 because 9 packages of 8 would not be enough

  12. becky says:

    Extra Mile: It would be cheaper to buy the buns at Cosco because you would need 4 packages of 20. 20 x 4=80. $3.75 x 4=$ 15.00. At the supermarket you would need 10 packages of 8.
    10 x 8=80. $2.00 x 10=$20.00. You would save $5.00 if you shop at Cosco.

  13. jacklyn says:

    76/8=9.5

    You will have to buy 10 packages because if you divide 76/8 you will get 9.5. So you would have to buy 10 packages but you will still have 4 left over.

  14. zach b says:

    They have to buy 10 packages if buns for the hamburgers for the family reunion.

    homework

    Extra Mile: I would buy the buns from Cosco because I would save $5.00.

  15. sarina says:

    the question to the problem is…

    8×9 which is 72+4 which is 76. So the family has to buy 10 packages of buns. 10 packages because for the extra four buns.

  16. jessica says:

    76-8=68 I got this answer by subtracting 76-8. The answer I got was 68.

  17. Emma says:

    Emma’s work:
    4
    76
    x 8
    ___
    608 Hamburger Buns

    Mrs.Spata,
    My answer for the question is 608 hamburger buns. As you can see above under “Emma’s Work” I multiplied 76 x 8.

  18. olivia says:

    8x?=76
    It says about how many packages should your family buy.
    8×8=64 and then add 8 more and you get 72 and that is just 9.You need 4 more. So the anwser will be about 10 packages.

  19. Jackie A says:

    Dear Mrs. Spata,
    I would buy 10 bags of buns if I were going to the family reunion. I would get 10 bags because if I did, I would have 4 left over. 8×10=80.
    I would want to buy buns from cosco because 4 bags of 20 buns equals 80 buns in all. the total amount of money I would spend is………..$15.25

    Your Student,
    Jacqulyn A

  20. anjali says:

    8 goes into 76, 9 times. 8×9=72. 76-72=4. 9 remainder is 4.
    I got my answer by doing long division. First I figured out how many times 8 goes into 76. I got 9.Then I did 8×9=72. Then I did 76-72=4. Finally I got 9 packages with a remainder of 4 buns.

  21. Taylor says:

    You need 10 bags of hamburger buns because 9 bags only have 72 buns because 9×8=72. So you would need 10 bags of hamburgers because 10×8=80. Even though 8×9 has less than 76 hamburger buns, you wouldn’t have enough. I know that 10 bags is enough because 10×8=80 and 8×9=72 and that is not enough buns.

  22. Aiman says:

    I would do 8x__=76.In the eights mutiplcation table nothing equals 76.So I know 8×7=56.So I would get 20 more buns.So I will buy 7 bags.But I will have 20 still remaning so I will need 3 more bags of buns.Then I will add 7+3=10.Then I will buys 10 bags of buns.That’s how I got my answer.By :)!:)!Aiman
    P.S. You are a great teacher.You rock.Bye I hope I get the answer right.

  23. nicholas says:

    I used my 8 times tables and I came up with 8 x 10 = 80
    I then used subtraction 80-76=4
    So I would have 4 buns left over.
    extra mile
    20 buns at costco is 3.75, I was buying 80 buns which is 4 packages.
    so 3.75 x 4 = 15.00
    8 buns at 2.00 at store. I would need 10 packages.
    so 10 x 2.00 = 20.00

    So Costco would be cheaper.

  24. Anthony B says:

    Buy 10 packages so you will have enough.

    It would be cheaper to buy a bulk bag at Cosco. It would be cheaper because at the super merket it would cost $.25 each. At cosco it would cost $.1875.

  25. anthonyb says:

    You should buy 10 packages. It would be cheaper to by buns at cosco because at the supermarket it costs $.25 for each bun, at cosco it costs $.1875 for each roll.
