Diego’s family car holds 14 gallons of fuel. Each day the car uses 0.6 gallons of fuel. A warning light comes on when the remaining fuel is 1.5 gallons or less. Starting from a full tank, can Diego’s family drive the car for 25 days without the warning light coming on? Explain or show your reasoning. *

20 days.

Step-by-step explanation:

The question must be when the light comes on.

Well, we must first know how much fuel must be consumed so that the light comes on and is calculated as follows:

14 gallons - 1.5 gallons = 12.5 gallons

That is to say that 12.5 gallons must be consumed at least for the light to come on.

Now, to calculate the number of days you must have the daily consumption account that is 0.6 gallons and the value calculated above, in the following way you can calculate the number of days:

12.5 gallons / (0.6 gallons / day) = 20 days.

The lights will come on at 20 days, that is, at 20 days, Diego's dad should fill the car with fuel.
