- Megan earns $20,000 per year plus 5% commission
on her sales. Laurie earns $32,000 per year plus
1% commission on her sales. Which system of
equations can you use to determine the amounts that
Megan and Laurie must sell s to receive equal pay p?
CD p + 0.5s = 20,000
p + 0.1s = 32,000
p = 0.05s + 20,000
p = 0.015 + 32,000
CD p = 5s + 20,000
p = s + 3 2 ,0 0 0
CD P + 5s = 20,000
p + s = 32,000- Your family is driving
