Question

A cab service charges a flat rate of $3.25 and an additional $0.75 per mile. Ashley has $10. What is the maximum number of miles Ashley can travel?

Answer 1

After paying for the flat rate, she has 10-3.25=6.75 left.

With 6.75 she can go for 6.75/0.75 = 9 miles

Note: solving by reasoning is often faster than mechanically forming an equation.
