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.
