A swimming pool has 30 gallons of water in it. Water was added to the pool at a rate of 5 gallons per second. Which equation models the relationship between t, The number of gallons of water, and W, The number of seconds water is being added to the pool?
A. t = W + 35
B. t = 35W
C. t = 5W + 30
D. t = 30W + 5

Respuesta :

Answer:

t=5W+30 or C

Step-by-step explanation:

The pool already has 30 in it so you would initially be adding it, not multiplying it to anything. Then since every second 5 gallons of water is being added to the pool, you add the 30 gallons the pool already contains to 5W.
