The salesman earning is an illustration of a piecewise function

The salesman earnings are: y = 500 + 0.12(x-1000); x > 1000 and y = 500; x <= 1000

How to determine the salesman total earnings?

From the complete question, the salesman earns a commission of 12% on total sales greater than 1000.

If the total sales is x, then the salesman total earnings (y) would be:

y = 500 + 0.12(x-1000); x > 1000

If otherwise, the total sales is not greater than 1000, then the total earnings would be:

y = 500; x <= 1000

Hence, the salesman earnings are: y = 500 + 0.12(x-1000); x > 1000 and y = 500; x <= 1000
