Using proportions, considering the cost of the taxi per mile, it is found that Gary traveled 9.375 miles, not including the first.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, the company charges 2.95 for the first mile and $0.3 per each 1/8 mile next = $2.4 per mile. After the first mile, he was charged a total of $25.45 - $2.95 = $22.5. Hence the number of miles is given by:
22.5/2.4 = 9.375.
