Pre-Cal Help?

Question

The fare for riding a cab is as follows $2.00 for the first mile or part, $0.25 for each additional mile or part.

Determine C(d) an equation representing the cost C of the ride in terms of the distance traveled.

For d≤1, C(d)=?
For d>1, C(d)=?
How much does it cost for a 40 mile ride?

Answer 1

hey I will gladly help you on this one.
for d ≤ 1 = C (d) = 2 x dollars in which x = the first mile or less
for d > 1 = C (d) = 2 (x) + .25 y in which y = number of miles after the first mile or less
for a 40 mile ride = 2 + .25 (39) = 11.75 dollars
