Answer:
d = 15c
Explanation:
Amount Xavier is paid per cell phone plan purchased = $15
d = Total amount Xavier is paid
c = number of cell phone plan he sells
The equation:
Total amount Xavier is paid = Amount Xavier is paid per cell phone plan purchased * number of cell phone plan he sells
d = 15 * c
d = 15c
For instance, If Xavier sell 4 cell phone plan
d = 15c
d = 15(4)
d = 60
Total amount Xavier is paid for selling 4 cell phone plans = $60
