a water tank holds 280 gallons. two percent of the water is lost at stream. how many gallons remain to be used ?
mart [117]
If you would like to know how many gallons remain to be used, you can do this using the following steps:

lost: 2% of 280 gallons = 2% * 280 gallons = 2/100 * 280 = 5.6 gallons

280 gallons - 5.6 gallons = 274.4 gallons

The correct result would be 274.4 gallons.
