Answer:

  15 weeks

Step-by-step explanation:

You want to know how long it will take Nicole to save $150 if she starts with $75 and adds $5 per week.

Savings

If w is the number of weeks Nicole saves $5, then her savings balance will be ...

  75 +5w

We want to find the value of w that makes this total 150:

  75 +5w = 150

  5w = 75 . . . . . . subtract 75 from both sides

  w = 15 . . . . . . divide by 5

It will take Nicole 15 weeks for her savings to total $150.
