Answer:
$135
Step-by-step explanation:
The profit is the revenue (selling price) - cost
Here, selling price per set is $1.75
Cost is $0.40
So, profit = 1.75 - 0.40 = $1.35 per set
If 500 set are sold, the total profit is:
500 * 1.35 = $675
20% of this profit (675) will go to school, so we need to find 20% of $675. We first convert the percentage to decimal and multiply with 675. Shown below:
20% = 20/100 = 0.2
0.2 * 675 = $135
Thus,
$135 goes to school
