Question

The water in a pool is evaporating at a rate of 2% per day. If the pool has 14,400 gallons in it today, how many gallons will it have in 8 days? Round your answer to the nearest whole number, if necessary.

Answer 1

evaporation rate = 2%= 0.02 ( decimal )

gallons today = 14,400

number of days = 8

Using the values given:

14,400 ( 1 - 0.02)^ 8

12,251

Answer:

In 8 days, the pool will have 12,251 gallons in.
