Question

Diego's family car holds 14 gallons of fuel. Each day the car uses 0.5 gallons of fuel. A warning light comes on when the raining fuel is 1.5 gallons or less. write an inequality to determine the number of days diego's father can drive the car without the warning light coming on.

Answer 1

0.5n < 12.5

n < 25 days

Explanation:

Total gallons of fuel = 14 gallons

Warning light comes on when the remaining fuel is 1.5 gallons or less

Gallons of fuel used without warning light = 14 gallons - 1.5 gallons

= 12.5 gallons

Gallons of fuel used per day = 0.5 gallons

Number of days = n

inequality to determine the number of days diego's father can drive the car without the warning light coming on.

0.5n < 12.5

n < 12.5/0.5

n < 25 days
