Aubrey can save $7 per week, so she can save $7 x 8 or $56
in 8 weeks. Because she already had $85 to begin with, the
total amount saved would be $56 + $85 or $141.

Answer 1

`Total\ Savings = 85 + 7 w` --- In w weeks

`Total\ Savings = \$141` --- In 8 weeks

Explanation:

Given

`Available\ Amount = \$85`

`Weekly\ Savings = \$7`

`Number\ of\ weeks = 8`

Required

Determine the amount of savings in w weeks

This can be calculated as thus:

`Total\ Savings = Available\ Amount + Weekly\ Savings * Number\ of\ weeks`

In this case;

w = Number of weeks

So, we have:

`Total\ Savings = 85 + 7 * w`

`Total\ Savings = 85 + 7 w`

When w = 8, we have

`Total\ Savings = 85 + 7 * 8`

`Total\ Savings = 85 + 56`

`Total\ Savings = \$141`
