Kelton Morrison · Answer 1

First you need to find the initial tuition, so multiply the increase by the years

500 x 6 = 3,000

Then subtract that from Wilma’s tuition

10,250 - 3,000 = 7,250

Use that and the rate of increase to create the equation

Tuition = 7,250 - 500x

Where x represents the number of years
