Shaniyah drives a truck for a living. While out on the road delivering fruit to a grocery store, she stops to fill up the gas tank. She puts 102.85 gallons of gas in the truck. If the tank holds 120 gallons of gas, how much gas was remaining in the tank before she filled it up

To find the amount of gas remaining in the tank before Shaniyah filled it up, we subtract the amount of gas she put in the tank from the tank's capacity.

Gas remaining = Tank capacity - Gas put in the tank
= 120 gallons - 102.85 gallons
= 17.15 gallons

Therefore, there were 17.15 gallons of gas remaining in the tank before Shaniyah filled it up.

To determine how much gas was remaining in the tank before Shaniyah filled it up, we need to subtract the amount of gas she put in the tank (102.85 gallons) from the total capacity of the tank (120 gallons).

Remaining gas = Total capacity - Gas filled
Remaining gas = 120 gallons - 102.85 gallons
Remaining gas = 17.15 gallons

Therefore, there was 17.15 gallons of gas remaining in the tank before Shaniyah filled it up.
