Answer:

The mileage for which the company A will charge more is 125

Step-by-step explanation:

Given as :

The charge of company A = 60 cents per mile

The charge of company B = 40 cents per mile + $75

Now , Let the number of miles driven = m

So, 60 m = 40 m + $ 75

∵ 1 $ = 100 cents

Or , 60 m - 40 m = 75 × 100 cents

Or, 20 m = 7500 cents

∴ m = [tex]\frac{7500}{20}[/tex]

or, Number of miles driven = 375 miles

The charge of company A = 60 × 375 = 22,500 cents

The charge of company B = 40 × 375 + 7500 = 22,500 cents

So, Here Both company charge is same

Now Let The mileage for which company charge more = m'

SO, 60 × (375 - m') = 40 × 375

or, 22500 - 60 m'= 15000

Or, 60 m' = 7500

So , m' = [tex]\frac{7500}{60}[/tex] = 125

Hence The mileage for which the company A will charge more is 125 Answer
