Answer:
Cici received $54.72 dollars in change
Step-by-step explanation:
$100 (what she payed with) - $45.28 (how much she spent) = $54.72 (how much she got back in change)
To find the cost per pound you simply divide the amount paid by the amount purchased
For Beef it would be:
$7.20 ÷ 2.0 = $3.60
For Pork it would be:
$8.10 ÷ 2.5 = $3.40
For Chicken it would be:
$9.80 ÷ 3.5 = $2.8
