A fuel tank of a vehicle is 80% full. After traveling some distance, only 30% of that fuel is left. The tank is then filled to its full capacity by putting in 19 gallons. What is the full capacity of the tank
**
let x=full capacity of the tank
x=19+fuel left in tank
x=19+30%*80%x
x=19+.24x
.76x=19
x=25
full capacity of the tank=25 gallons
