: Can you help with this question on writing a cost function, assuming the relationship is linear: A cab company charges a base rate of 41.50 plus 15 cents per minute. Let C(x) be the cost in dollars of using the cab for x minutes.
A. C(x)=1.50x+0.15
B. C(x)=1.50x-0.15
C. C(x)=0.15x-1.50
D. C(x)=0.15+1.50 This question is from textbook Finite Mathematics with Aplications

A cab company charges a base rate of 41.50 plus 15 cents per minute. Let C(x) be the cost in dollars of using the cab for x minutes.
:
That 41.50 must mean $1.50
;
Cost = Cost for x miles + fixed cost
C(x) = .15x + 1.50; it may be d and you forgot the x in there
