Answer:
c. 7h + 43 = 64
Step-by-step explanation:
If h is the hourly fee, then 7h is the fee for renting the equipment 7 hours. That added to the initial fee of $43 gives the total charge of $64.
7h + 43 = 64 . . . . . appropriately models the charges
___
The solution is h = (64 -43)/7 = 3. The hourly fee was $3.
