$10 is earned for every 3 items sold
The students sold 321 items
There are 2 ways to do this, the first way is to divide the total number of items sold with the amount of every item sold, so:
321 (total items sold) ÷ 3 (items sold in a bundle) = 107
Next, multiply 107 with $10 to find out the total amount of profit.
107 x $10 (per 3 items in a bundle) = $1,070 (total profit)
The next step is to find out how much every single item costs.
Simply divide the number of cash made by selling the bundle of 3.
$10 ÷ 3 = $3.333 (price per item)
Next, multiply $3.333 with the total number of items sold (321), so:
$3.333 x 321 = $1,070 (total profit)
