Answer:

$2,480

Step-by-step 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:

$\dfrac{x}{2,400}=\dfrac{100}{75}\\ \\75x=2,400\cdot 100\\ \\75x=240,000\\ \\x=3,200$

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

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