Question

TRANSPORTATION The cost of riding in a cab is $3.00 plus $0.75 per mile. The equation that represents this relation is y=0.75x+3, where x is the number of miles traveled and y is the cost of the trip. Find and interpret f(17).

Answer 1

f(17) = $15.75

The amount it takes for a trip of 17 miles is $15.75

Explanation:

Here, we want to calculate f(17)

The equation is given as;

y = 0.75x + 3

For f(17), substitute x for 17

y = 0.75(17) + 3

y = 12.75 + 3

y = $15.75

What f(17) means is that the ride was for 17 miles

$15.75 is for a trip of 17 miles
