Let's break down the total amount Mr. Gomez spent on jeans:
2 pairs of jeans * $25.75 per pair = $51.50
Now, let's subtract this amount from the total he spent to find out how much the pair of shoes cost:
Total amount spent - Amount spent on jeans = Cost of shoes
$80.25 - $51.50 = $28.75
So, the pair of shoes cost $28.75.
