First find the amount of each payment:

The total cost will be 40 payments plus service charges.

The percentage is the service charge divided by total cost:

- Given - <u>an </u><u>equation </u><u>in </u><u>it's</u><u> </u><u>general </u><u>form</u>
- To do - <u>convert </u><u>the </u><u>given</u><u> </u><u>equation</u><u> </u><u>into </u><u>a </u><u>form </u><u>that </u><u>is </u><u>easy </u><u>to </u><u>solve</u>
<u>Given </u><u>equation</u><u> </u><u>-</u>

You take 8 of something and add 2 more making 10 of something.
In order to solve the amount of each solution, we need to set up equations. We do as follows:
Let x = solution with 32% sodium
y = solution with 12% sodium
Overall balance
x + y = 50
Component balance
.32x + .12y = 50(.20) =10
Solving simultaneously,
x = 20
y = 30
Hope this answers the question. Have a nice day.
