Answer:
240 miles
Step-by-step explanation:
Let's set up an equation for each vehicle:
Car Agency:
y = .25x + 240
Where y is the total cost and x is the number of miles driven
Minivan Agency:
y = .40x + 180
Where y is the total cost and x is the number of miles driven
Now, let's find the number of miles it will take for the total cost of the vehicles to be the same. In order to this, set the equations equal to themselves.
Solve:
y = .25x + 240
y = .40x + 180
.25x + 240 = .40x + 180
Subtract .25x on both sides:
.25x + 240 = .40x + 180
-.25x -.25x
240 = .15x + 180
Subtract 180 on both sides:
240 = .15x + 180
-180 -180
60 = .25x
Divide by .25 on both sides:
60 = .25x
/.25 /.25
240 = x
Therefore, after 240 miles, the total charge for each vehicle will be the same.
