Answer:

the tank can hold 12.5 gallons when it is full

Explanation:

Let's assume

tank can hold 'x' gallons when it is full

we are given

The gas gauge in a car shows it has 40% of a tank of gas

So, gas in car is


=(40)/(100)* x

and we have

the car has about 5 gallons

so, we can set it equal

and then we can solve for x


5=(40)/(100)* x


5=(4)/(10)* x


5=(2)/(5)* x

Multiply both sides 5


5* 5=5* (2)/(5)* x


5* 5=2x


25=2x

we get


x=12.5

So, the tank can hold 12.5 gallons when it is full
