use the expression r+0.12m to calculate the cost of renting a car. The basic rate is r. The number of miles driven is m.
1. the basic rate is $15.95. the car is driven 150 mi.
2. the basic rate is $32.50. the car is driven 257 mi.
Add the basic rate and 0.12 times the miles driven.
1. 15.95 + 150*0.12 = 15.95 + 18.00 = ?
2. Your turn
$33.95
To calculate the cost of renting a car using the expression r+0.12m, where r is the basic rate and m is the number of miles driven, we can substitute the given values and perform the calculations.
Let's solve the two scenarios:
1. The basic rate is $15.95, and the car is driven 150 miles.
Substitute r = $15.95 and m = 150 into the expression:
Cost = 15.95 + 0.12 * 150
= 15.95 + 18
= $33.95
Therefore, the cost of renting the car in this scenario is $33.95.
2. The basic rate is $32.50, and the car is driven 257 miles.
Substitute r = $32.50 and m = 257 into the expression:
Cost = 32.50 + 0.12 * 257
= 32.50 + 30.84
= $63.34
Therefore, the cost of renting the car in this scenario is $63.34.
