Answer:
c(h) = 50 +10h
c(4) = 90 . . . . . it costs $90 to rent the truck for 4 hours
Step-by-step explanation:
The problem statement tells you the total charge is the sum of $50 and a charge of $10 per hour. That is, for h hours, the total charge is ...
c = 50 + 10h
In functional form, this is ...
c(h) = 50 +10h . . . . . . total charger for a rental of h hours
__
The function value with an input of 4 is ...
c(4) = 50 +10·4
c(4) = 90
Since the input is the number of hours of rental, and the function value is the total charge, this represents the total charge for a rental of 4 hours.
