Answer:
Step-by-step explanation:
Let the renter drives 'x' miles
Company A:
Rental cost = 30 + 0.15x
Company B:
Rental cost = 20 + 0.20x
Given rental cost are same
20 + 0.20x = 30 + 0.15x
Subtract 20 from both sides
20 + 0.20x - 20 = 30 + 0.15x - 20
0.20x = 10 + 0.15x
Subtract 0.15x from both sides
0.20x - 0.15x = 10 + 0.15x - 0.15x
0.05x = 10
Divide both sides by 0.05
0.05x/0.05=10/0.05
x = 1000/5
x = 200
a) The renter has to drive 200 miles
b) Rental cost charged by company A = 30 +0.15*200
= 30 + 30
= $ 60
Rental cost charged by company B = 20 + 0.20**200
= 20 + 40
= $ 60
