A water tank holds 280 gallons. two percent of the water is lost at stream. how many gallons remain to be used?

2% lost.

Left = 100% - 2% = 98%

98% of 280

= 0.98*280

= 274.4

274.4 gallons remain to be used.

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.
