Question

Martin works at an aquarium shop. One day, he arrives to

work, and his boss asks him to clean a 180-gallon aquarium. He first
needs to drain the water before cleaning the tank. While draining the
water, Martin observes that after 1 hour, 150 gallons of water remain in
the tank; after 2 hours, 120 gallons remain; and after 3 hours, 90 gallons
remain in the tank.
(A)Create the function that models the number of gallons in the tank.

Answer 1

g(x)= x-30

Step-by-step explanation:

g(180)= 180-30= 150 gallons in 1 hour

g(150)= 150-30= 120 gallons in 2 hours

g(120)= 120-30= 90 gallons in 3 hours

g(90)= 90-30= 30 gallons in 4 hours

g(30)= 30-30= 0 gallons in 5 hours
