Answer: 7115 gallons

Step-by-step explanation:

Given: Water was drained from a swimming pool.

The equation [tex]\hat{y}=14590\cdot0.95x[/tex] estimates the number of gallons of water remaining after x hours from the time it started draining.

At x=14, we have

[tex]\hat{y}=14590\cdot0.95^{14}=7115.1779453\approx7115[/tex]

Hence, there were 7115 gallons of water in the pool after 14 hours of draining.
