Question

A taxicab company charges $3.00 per ride and $0.75 for each mile driven. Your budget allows you to spend more than $10.00 but less than $20.00 to go from the airport to the beach. What is the greatest number of miles you can travel and stay within your budget? Round your answer to the nearest whole mile that satisfies the inequality.
A 23 miles
B 9 miles
C 22 miles
D 10 miles

Answer 1

The inequality is: x*0.75 + 3.00  < 20.00, where x represents the number of miles. When you solve the inequality, you get 22.66 miles. When you round up to 23 miles, you don't satisfy the inequality, so you have to round down to 22 miles.

Answer: (C) 22 miles
