A helicopter company charges $85 for the first kilometer of a trip and $5 every kilometer after that. If the total cost of a trip was $365, how many kilometers were flown?
A. 55
B. 56
C. 57
D. 58
E. 59
The OA is C.
Experts, can I say that the total cost will be determined by the formula, T = 85+5k ( where k represent the additional kilometers after the first kilometer of the trip)?
Then, 365 = 85 + 5k, the value of k will be, k = (365 - 85) / 5 = 56 kilometers, that's mean that the total kilometers of the trip was 57. Right?
Experts, any suggestion about this PS question? Thanks in advance.
