Question

Every year Aiden uses income from his job to pay for 75% of his college tuition. Next year’s tuition will be $720 more than this year’s, and Aiden will pay $2400. How much is this year’s tuition?

Answer 1

$2,480

Explanation:

Let $x be next year tuition. Aiden will pay $2,400, that is 75% of $x.

$x - 100%

$2,400 - 75%

Write a proportion:

`(x)/(2,400)=(100)/(75)\\ \\75x=2,400\cdot 100\\ \\75x=240,000\\ \\x=3,200`

Next year’s tuition will be $720 more than this year’s, then this year tuition is

`\$3,200-\$720=\$2,480`
