Question

An employer has a daily payroll of 1225.00 when employing some workers at 80.00 per day and others at 85.00 per day. When the number of 80.00 workers increases by 50% and the number of 85.00 workers is decreased by 1/5, the new daily payroll is 1540.00. How many were originally employed at each rate?

Answer 1

I got the two equations:

1225=80x+85y and 1540=120x+68y

Then used the substitution method and ended up with

x=20.37 and y=-4.76

So if did this correct than x and y should equal the number of workers originally employed at each rate.

Did I do this right?

Answer 2

still stuck
