Explanation:

if diego car can hold 14 gallons and eveery day they use 0.6 0.6x25 is 15 which means that they can drive 15 days in all so 15-1.5 13.5 so they can only drive for 13.5 days

Answer:

No, Diego's family cannot drive the car for 25 days without the warning light coming on.

Explanation:

Find how much fuel they will use in 25 days by multiplying 25 by 0.6, since the car uses 0.6 gallons each day:

25(0.6)

= 15

Subtract this from 14 to see how much fuel will remain, starting from a full tank:

14 - 15

= -1

The number is negative, meaning that driving the car for 25 days will use up all of the fuel. So, the warning light will come on.

No, Diego's family cannot drive the car for 25 days without the warning light coming on.
