Answer:
<h3>5 hours</h3>
Step-by-step explanation:
Given the expression for the amount of water needed to completely fill the hot sub expressed as;
H(x) = 400 – 50x
x is the total number of hours
To get the number of hours it has been filling if it is still has 150 gallons to go, we will substitute h(x) as 150 and find x as shown;
150 = 400 - 50x
150 - 400 = -50x
-250 = -50x
x = -250/-50
x = 5
Hence it has been filling for 5 hours
