Step 2: Find slope m

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.
