To find the bill for the Fox family, we need to substitute the amount of electricity they used (872 kWh) into the function C(e) and calculate the total cost.
Given: C(e) = $0.16e + $24.54
Substituting the value of e = 872 into the function:
C(872) = $0.16 * 872 + $24.54
= $139.52 + $24.54
= $164.06
Therefore, the bill for the Fox family is $164.06.
So, you were correct in thinking that the answer is C.
