Let The mileages for which company A charge less than company B = y
<u>Now, According to question</u>
Charges of company A = charges of company B
i.e i = I + 0.90 × x
Or, $110 = $65 + 0.90 × x
Or, $110 - $65 = 0.90 × x
Or, $45 = 0.90 × x
∴ x =
i.e x = 50
i.e Company B driven x = 50 miles
So, The mileages for which company A charge less than company B = y
