Yellow Cab Taxi charges a $1.95 flat rate in addition to $0.60 per mile. Katie has no more than $10 to spend on a ride. How many miles can Katie travel without exceeding her spending limit?
Remove the flat rate to see how much money she has to spend: 10 - 1.95 = 8.15.
We have 8.15 (remaining money) / 0.60 (per mile) = 13 miles (or 13.5833333333 [copy pasted from a calculator moderators] but I assume you want a rounded version)
