adobe rent a car company charges a $50 rental free ,$20 for gas and $0.20 per mile driven for the same car vamos card charges $5

Ronch [10]

Answer:

x = 150 miles

Cost = $100

Step-by-step explanation:

Company A = 50 + 20 + 0.20x

= 70 + 0.20x

Company B = 55 + 0.30x

Where,

x =number of miles

find the number of miles for which the companies charge will be the same

Equate the charges of both companies

70 + 0.20x = 55 + 0.30x

70 - 55 = 0.30x - 0.20x

15 = 0.10x

Divide both sides by 0.10

x = 15 / 0.10

= 150

x = 150 miles

The number of miles for which the companies charge will be the same is 150 miles

Substitute 150 miles into any of the companies charges to find the charge

Company B = 55 + 0.30x

= 55 + 0.30(150)

= 55 + 45

= $100
