Answer :

The amount of money that Alex will use to purchase the 5 x 7 print would be = $11.89.

What is online printing service?

An online printing service is the service that is rendered online that helps interested individuals to prepare their printed paper works.

The number of 4 x 6 prints(X) purchased by Alex = 29

The number of 5 x 7 prints (y) purchased by Alex = 16

The total amount he paid for the whole service = $22.89

The cost of 5 x 7 prints can be calculated using this expression;

22.89 - 0.84 = 22.05/2 = 11.025

Therefore the cost of 5×7 prints = 11.05+ 0.84 = $11.89.
