Martin's car holds 24 gallons of fuel. Each day the car uses 1.5 gallons of fuel. A light comes on when the tank has 2.5 gallons of fuel or less.
Write and solve an inequality to determine the number of days, d, Martin can drive the car without the warning light coming on.
Use: 24, 1.5d, and 2.5 in your answer
1.5d + 2.5 < 24
d = 14.3 or less days
