Answer:
a. C(x) = $3.50 + $0.10x. b. distance traveled c. cost of the taxi ride d. $0.10 per mile
Explanation:
A. Let C be the cost of the taxi ride and x be the distance traveled in miles. Since there is a base charge of $3.50 and a charge of $0.10 per mile, the cost of the ride is thus
C(x) = $3.50 + $0.10x.
B. The independent variable represents the distance traveled in miles since it is the parameter being measured.
C. The dependent variable represents the cost of the taxi ride, since it is value depends on the parameter (the distance) being measured.
D. The rate of change in this scenario is the $0.10 per mile
