Math Question
![The Central Texas drought causes the water level of area lakes to exponentially decay by a rate of \( 20 \% \) per year. If Lake Travis had 300 billion gallons of water in 2010, how many billions of gallons are left three years later?
First, complete the equation:
Remaining Amount \( =300(1-[?])^{[]} \)](https://d3hlidq5bf9vg0.cloudfront.net/app-server-student/2022/3/23/f0f07921-ab4e-48cd-b81d-f98ed0441f25.png "The Central Texas drought causes the water level of area lakes to exponentially decay by a rate of \( 20 \% \) per year.
