Step-by-step explanation:
A
160 >= 20 + 35x
x being the number of hours renting the canoe.
and we have to pay first $20 flat, no matter what. and then the hourly rate begins to "tick".
B
140 >= 35x
x <= 4
and actually, to make practical sense,
0 < x <= 4
as we want to apply this only, if we truly rent a canoe. 0 hours renting (or even negative numbers) does not make any sense.
C
with the given budget of $160 we can rent a canoe for maximum 4 hours.
