Answer:
$1.9
Step-by-step explanation:
2 pound bag (when he bought) =.30×2=$0.6
when he sells, price is $2.50.
Profit for each bag= $2.5-$0.6=$1.9
Total cost of painting 225 cm² will be:
Cost=(total area)×(cost per cm²)
area=225 cm²
cost per cm²=$0.12
thus the total cost will be:
Cost=0.12×225=$27
Answer: $27
