To determine for which number of miles the cost of renting a vehicle from Rent A Ride is less than the cost from We Got Wheels, we can set up an inequality.
Let \( x \) be the number of miles driven.
Cost from Rent A Ride:
Rent A Ride has a flat fee of $55, regardless of miles:
\[
\text{Cost}_{\text{Rent A Ride}} = 55
\]
Cost from We Got Wheels:
We Got Wheels charges a flat fee of $38 plus $0.20 per mile:
\[
\text{Cost}_{\text{We Got Wheels}} = 38 + 0.20x
\]
We want to find when Rent A Ride's cost is less than We Got Wheels' cost: \[ 55 < 38 + 0.20x \]
Now, solve the inequality:
-
Subtract 38 from both sides: \[ 55 - 38 < 0.20x \] \[ 17 < 0.20x \]
-
Divide both sides by 0.20: \[ \frac{17}{0.20} < x \] \[ 85 < x \]
This simplifies to: \[ x > 85 \]
Thus, Rent A Ride is less expensive than We Got Wheels when the number of miles driven \( x \) is greater than 85 miles.
