ABC Taxi charges $1.75 plus 10¢ per mile while Friendly Taxi charges $2.25 plus 7¢ per mile. You want to know at what distance the two taxi companies would charge the same amount, and which company would be cheaper for shorter distances.

Looks like you need to setup an algebraic equation with one variable, d, for distance.
for example
1.75 + 0.10 d = 2.25 + 0.07 d

if you go zero miles, who is cheaper ?)
