Write an equation that can be used to determine c, the total amount in dollars that the cleaning company charges to clean a house in h hours.

c = 15 + 17h
c = 20h
.
20h = 15 + 17h
3h = 15
h = 5 at 5 hours both companies cost the same
.
NOTES:
anything over 5 hours 15+17h is cheaper.
anything under 5 hours 20h is cheaper
