Question

Ali hires a car. There is a fixed charge of $170 and then an extra charge of $40 for each day that the car is hired. Write down a formula for the total cost T, in dollars, when the car is hired for n days.

Answer 1

f ch = fixed charge

f ch = $170

e ch = extra charge

n = day

e ch × 1n = $40

170 + (40×n) = total cost
