Question

a big storage tank contains 1680 gallons of gasoline. 25 cars filled their tanks with 24 gallons of gas each. 35 trucks put 30 gallons of gas in each of their tanks. how many gallons of gas are left in the big storage tank?

Answer 1

30 gallons of gas is left

Explanation:

1680 is what we start with

25 filled with 24

25*24=600

35 filled with 30

35*30= 1050

So we take away what we used

600+1050= 1650

We started with 1680

1650 got taken away so

1680-1650= 30

30 gallons are left

Answer 2

• 30 gallons of gas are left in the big storage tank

---------------------------------

Initial volume of gas in the storage tank is 1680 gallons.

Cars took:

• 25 × 24 = 600 gallons

Trucks took:

• 35 × 30 = 1050 gallons

Gas left in the storage tank:

• 1680 - (600 + 1050) =
• 1680 - 1650 =
• 30 gallons
