Question

. Kim wants to buy a DVD player that costs $175. She already has saved $40 and plans to continue saving an additional $15 each week. Write an algebraic expression that represents the total amount of money Kim has saved after any number of weeks. Expression?

Answer 1

Step-by-step explanation:

Let 'y' be the amount of money Kim saves and let 'x' be the number of weeks.

Kim has initialy $40, so when the number of weeks x = 0, the amount of money y = 40.

Then, for each week she saves an additional $15, so when the number of weeks x = 1, she has saved $15 more than before, and when it's 2 weeks she's saved $30 more and so on.

Answer:

The expression that represents the total amount of money Kim's saved after 'x' weeks is:

`y=15x+40`
