MODELING REAL LIFE The cost (in dollars) of a car ride from a ride-sharing company during regular hours is modeled by
f(x) = 2.30x, where x is the number of miles driven. The cost of a ride during high-demand hours, including a tip, is $5 more
than 120% the cost during regular hours. What is the cost of a 6-mile ride during high-demand hours?
The cost of a 6-mile ride during high-demand hours is $___

Answer 1

Using a proportional relationship, we have that:

The cost of a 6-mile ride during high-demand hours is $21.56.

What is a proportional relationship?

A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:

y = kx

In which k is the constant of proportionality.

In this problem, the function is:

f(x) = 2.30x.

The cost for 6 miles is:

f(6) = 2.30 x 6 = $13.8.

5 plus 120% of that is:

1.2 x 13.8 + 5 = $21.56.

The cost of a 6-mile ride during high-demand hours is $21.56.
