A water park has pools, slides, and rides that, in total, make use of gallons of water. They plan to add a ride that would make use of an additional gallons of water. Use scientific notation to express the total gallons of water made use of in the park after the new ride is installed.

In the current setup, the water park uses gallons of water, and the new ride would use an additional gallons of water.

To find the total gallons of water used after the new ride is installed, we add these two quantities:

gallons + gallons = gallons

Expressing this in scientific notation where gallons is equal to x in scientific notation:

x + x = x

Therefore, the total gallons of water used in the park after the new ride is installed is x gallons in scientific notation.
