First we define variables. x = number of miles. y = total cost in $ We write the equation that adapts to the problem: y = 2.08x + 4.50 For y = 34.50 we have: 34.50 = 2.08x + 4.50 We clear x: x = (34.50-4.50) / (2.08) x = 14.4 miles Answer: You can travel from the airport by taxi for 34.50 about 14.4 miles.
