A taxi driver charges $4.50 for the first mile and $0.25 for each additional mile. Isabella pays $14.00 for a taxi ride. How many miles was Isabella’s ride?

From the question, we can find the expression for the money Isabella needs to pay, as follows:


\text{money}=4.5\text{ + (k-1)0.25}

Where k is the amount of miles. We know that she paid $14.00, so we can find the amount of miles:


4.5+(k-1)*0.25=14\rightarrow(k-1)*0.25=14-4.5\rightarrow k-1=(9.5)/(0.25)\rightarrow k=38+1\rightarrow k=39

So the taxi drove 39 miles.
