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
