Answer:
The hourly fee for rototiller is $3 per hour.
Step-by-step explanation:
We are given the following in the equation:
The rental company charged an initial fee of $43 with an additional fee per hour.
Let h represents the hourly fee.
The family paid $64 after renting the rototiller for 7 hours.
Thus, we can write the equation:
[tex]43 + 7h = 64[/tex]
Solving the equation, we get,
[tex]43 + 7h = 64\\7h = 64-43\\7h = 21\\\Rightarrow h = 3[/tex]
Thus, the hourly fee is $3 per hour.
Equation:
[tex]C(x) = 43 + 3x[/tex]
where C(x) is the cost function and x is the number of hours rototiller is rented.
The hourly fee for rototiller is $3 per hour.
