Question

The total charge for a taxi ride in NYC includes an additional fee of $3.75 plus $1.25 for every half mile traveled Jody took a taxi and the ride cost exactly $12.50 how many miles did you travel in the taxi

Answer 1

You can write a relationship where x will be the distance traveled in 12 miles:
3.75+1.25⋅x=12.5
solve for x:
x=12.5−3.751.25=7
but x corresponds to 12 miles so that Jodi traveled 7⋅12=3.5 miles
