Answer:
B. $5.08
Step-by-step explanation:
First find out how much the supermarket pays per dozen of eggs.
$8.00 / 12 dozen cartons per case = $0.66666
It costs the supermarket approximately $0.67 per dozen
Next find out the profit per dozen of eggs sold
$1.09 store price - $0.67 price store pays = $0.42
The supermarket profits about $0.42 per dozen sold
Finally find out the profit per case of eggs
12 dozen cartons * $0.42 profit per carton = $5.04
The supermarket makes about $5.04 per case so the best answer of the choices would be B. $5.08.
Multiplying everything and combining if needed, the product is, 15a^5b^15
