Question

Kate is saving to take an SAT prep course that cost $350. So far, she has saved $180, and she adds $17 to her savings each week, How many more weeks must she save to be able to afford the course(show work)

Answer 1

About 19 maybe 20 because 350$ Is her goal then subtract 180$ From 350 because she already has that money then you can divide the remaining by 7 because there are 7 days in a week

Answer 2

10 weeks

Explanation:

SAT prep course costs = $350

Kate has saved = $180

She adds to her savings each week = $17

Let the number of weeks to save enough money = x

180 + (17x) = 350

17x = 350 - 180

17x = 170

x =
`(170)/(17)`

x = 10 weeks

It takes 10 weeks to save enough money to be able to afford the course.
