Help w/math problem please!!! :)

Answer 1

Answers: 
a.) 17t + 200
b.) 93 minutes

Explanation:
The initial volume of the pond is 200 gallons, so that is the y-intercept and included in the equation. The rate of 17 gal/min is written as 17t if t = time. 
The full equations is 17t + 200. 

To find when the pond will fill up you simply make 1781 equal to the equation:
1781 = 17t + 200 
Then solve for t:
1781 – 200 = 17t + 200 – 200
1581 = 17t 
1581 ÷ 17 = 17t ÷ 17
93 = t
