872(.16) + 24.54
= 164.06
C(e) = $0.16e + $24.54,
where e is the amount of electricity used in kilowatt-hours (kWh) and C(e) is the total cost. If the Fox family used 872 kWh of electricity last month, how much was their bill?
A. $164.06
B. $148.06
C. $172.06
D. $139.52
I think C, but I'm not sure
= 164.06
.16 ( 872 ) + 24.54
= 139.52 + 24.54
= 164.06
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.
