Step-by-step explanation:

Step-by-step explanation:

So our equation would be:

12.00x + 8.50y = 324.50

x + y = 32 hours

lets set the last one to x = 32 - y and plug it in.

12(32-y) + 8.5y = 324.5

384 - 12y + 8.5y = 324.5

subtract 384 from both sides and add y to each other:

-3.5y = -59.5

Divide by -3.5

y = 17 hours worked
