Answer:

14

Explanation:

to determine the answer

Subtract the amount she wants to tip from the total amount of money she wants to spend

$27.50 - $4 = $23.50

Let m = total miles

the total miles she intends to drive can be determined using this equation

$23.50 = $6 + $1.25m

Collect like terms

$23.50 - $6 = $1.25m

$17.50 = £1.25m

Solve for m

17.50 / 1.25 = 14
