$5.30(C)+8.80(a) =1050.70

Question

Solve for a.

Answer 1

Treat 'a' as if it were a number. How would you deal with it that way?

5.30 * C + 8..80 * (some number) = 1050.70

We would subtract the product of 8.80 * a, right? So do that...

We end up with

5.30 * C = 1050.70 - 8.80 * a

Now we are almost finished. If we want to solve for C (a.k.a. isolate C), we need to divide both sides by 5.30. Be sure to put some parenthesis around the right side before you divide

C = (1050.70 - 8.80 *a)/ 5.30

I hope this helps!
