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.
Answer:
Net power = 20kW
B.) $128
Step-by-step explanation:
Given that :
Coefficient of performance = 2.5
Rate = 20kW
The net power required to operate the heat pump :
Energy delivery rate / Coefficient of performance
= 20kW / 2.5
= 8kW
B.) Given that electricity cost equals $0.08 per kW
If pump operates for 200 hours
Total energy used in kWhr :
8kW * 200= 1600kW
Cost per kW = $0.08
1600 * 0.08 = $128
