The per-capital consumption of bottled water wa 5 gallons in 1990 and has been increasingly yearly by a factor of 1.083.
What was the per capital consumption of bottled water 13 years later?
*round the answer to three decimal places *
Water consumption in the year 2003 was _____ gallons.
5 * 1.083^13
Scott, preach you!
To calculate the per capita consumption of bottled water 13 years later, we need to multiply the initial consumption (5 gallons) by the increasing factor (1.083) for 13 times.
The formula for calculating the per capita consumption after a certain number of years is:
New consumption = Initial consumption * (Increasing factor)^Number of years
Let's apply this formula to the given problem:
New consumption = 5 gallons * (1.083)^13
Using a calculator or a spreadsheet, we can calculate the answer:
New consumption ≈ 5 * (1.083)^13 ≈ 9.804 gallons
Therefore, the per capita consumption of bottled water 13 years later (in 2003) was approximately 9.804 gallons.
