Answer 1

(D) No, the answer is not reasonable. It should be about 10 pounds.

Explanation:

Hotdog = 4 2/5 pounds

Hamburger = 3 1/2 pounds

Chicken = 2 3/10 pounds

Total

= 4 2/5 + 3 1/2 + 2 3/10

= 4 4/10 + 3 5/10 + 2 3/10

= 9 12/10

= 10 2/10

= 10 1/5

Answer 2

D. No, the answer is not reasonable. It should be about 10 pounds.

Explanation:

hot dogs : 4 2/5 lbs

hamburger : 3 1/2 lbs

chicken: 2 3/10 lbs

Rounding to the nearest 1/2 pound

hot dogs : 4 1/2 lbs

hamburger : 3 1/2 lbs

chicken: 2 1/2 lbs

------------------------------

9 + 3/2

10 1/2 lbs

This is a little high since we rounded up on the hot dogs and the chicken

The estimate is not reasonable, it is around 10 lbs
