Question

The total charge for a taxi ride in NYC includes an initial fee of $3.75 plus $1.25 for every `1/2` mile traveled. Jodi took a taxi, and the ride cost her exactly $12.50. How many miles did she travel in the taxi?

Answer 1

I got `3.5` miles

Explanation:

We can write a relationship where `x` will be the distance travelled in `1/2` miles:
`3.75+1.25*x=12.5`
solve for `x`:
`x=(12.5-3.75)/1.25=7`
but `x` corresponds to `1/2` miles so that Jodi travelled `7*1/2=3.5` miles
