Answer:
<u>$4,680</u>
Step-by-step explanation:
<u>Rate</u> : 10 dollars a week
- Per year : 10 x 52 = $520
- 9 x 520 = $4,680
You will have saved up <u>$4,680</u> in 9 years.
Ok so this is how you do it.....
You need to get x by itself.
8x + c = k
Subtract c.
8x = k - c
Divide 8 from both sides.
x = k - c / 8
