Question

Marisa wants to buy a new XBOX that costs $300.00. She already saved $25.00 and plans to save an additional $10.00 per week. Write an expression that shows the amount of money Marissa has saved after ANY number of weeks. (Remember no equal sign! )

Answer 1

10x+25

Explanation:

The answer is 10x+25 because 25 is the initial value, which is the y intercept. Then, since she saves 10$ per week, it is 10*x, x representing the number of weeks.

Answer 2

25 + 10x

Explanation:

First, add the base $25 from the start.

Next, add $10 per week. The number of weeks is the unknown, and is represented by x, giving 10x.

Put them together, you get 25 + 10x.
