pool has 45000 gallons. It loses 780 gallons per hour, so the amount at any given time:
45000 - 780h, where h is the number of hours.
The chemical could be added once the amount of gallons in the pool hits 15000. So the equation to solve:
45000 - 780h = 15000
solve:
30000 = 780h
38.46 = h
It will take about 38.46 hours before chemical could be added. It will not take longer than 2 days because 2 days is 48 hours, and we only need about 38 hours.
Let’s rethink the question with functions. If f(x) = y then y should be changing by the value of x.
0.005 would be 5/1000 because how I know if it is 10ths or 100ths or 1000ths I count all the number on the right side of the decimal, hoped this could help!
Answer: That would be a vertical pair and X is 38
