A fuel tank has a capacity of 240 gallons. After using 65% of it, how many gallons are left?

To determine how many gallons are left in a fuel tank with a capacity of 240 gallons after using 65% of it, you start by calculating how much fuel has been used.

First, find 65% of 240 gallons. This is done by multiplying 240 by 0.65:

[

240 \times 0.65 = 156 \text{ gallons}

]

Next, subtract the amount used from the total capacity to find out how much is left:

[

240 - 156 = 84 \text{ gallons}

]

This calculation shows that after using 65% of a 240-gallon tank, 84 gallons remain. Thus, the correct answer accurately reflects the remaining quantity of fuel in the tank.
