Answer:

Brandy will save $315 in 21 weeks.

Step-by-step explanation:

Framing algebraic expressions:

       Let x be the number of weeks.

       If in a week, he saves $15, then in x weeks he will save 15x.

         15x = 315

To find the number of weeks, divide 315 by the money saved in a week.

            x = 315 ÷ 15

            x = 21

21 weeks.
