Question

A student at the mall purchased 4 shirts at an average price of $14 per shirt. If the student then purchased 2 of the same shirt in different colors but the same price, what would the price of the 5th and 6th shirt be if the average cost per shirt changed to $18

Answer 1

$26 each

Explanation:

To find the price of shirt 5 and 6, we first need to get the total amount spent for the first 4 shirts.

Initial amount = 4 x 14

Initial amount = $56

Now that we have the total price of the first 4 shirts, we then find the price of the shirts including the 5th and 6th shirt if the average cost per shirt shifted to $18.

Total amount = 6 x 18

Total amount = $108

We now then subtract the new amount to the initial amount to find the price of the 5th and 6th shirt together.

Total Shirt Price = $108 - $56

Total Shirt Price = $52

Now we divide the Shirt Price by two since there are two additional shirts.

Shirt Price = 52 / 2

Shirt Price = $26 each

So the 5th and 6th shirt both cost $26 each.
