Diego's family cannot drive the car for 28 days without the warning light turning on.

Step-by-step explanation:

Since the car uses 0.6 gallons per day, and Diego's family has been driving the car for 28 days, that means the total amount of fuel used is gallons. To determine whether the warning light will be on or not, subtract the total amount of fuel - 18 gallons - by the amount of fuel already used.
