Answer:
$26 each
Step-by-step 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.
