Answer:
$216.
Explanation:
Divide for the cost of 1 sweater, 72 divided 8, $9.
Divide $288 by 8, to get cost they sold each sweater, $36.
So the store sold each sweater $36 having bought each for $9.
Subtract $9 from $36 to get profit per sweater, $27.
Then multiply $27 by 8 for the total profit, $216.
