Answer:

My total savings was = $58.33

Step-by-step explanation:

Given:

12% of my savings was = $7.00

To find my total savings.

Solution:

Let the total savings in dollars be = x

12% of the total savings will be  = 12\%\ of\ x

12% of my savings was = $7.00

So, we have:

12\%\ of\ x=7

0.12x=7

Solving for x to get my total savings.

Dividing both sides by 0.12

\frac{0.12x}{0.12}=\frac{7}{0.12}

∴ x=58.33

Thus, my total savings was = $58.33
