Apump removes 1500 gal of water from a pool at a constant rate of 40 gal/min. which equation models the amount of water y in the pool after t minutes?

y = 40t

Step-by-step explanation:

A pump removes 500 gallons of water at  a constant rate of 40 gallon/min.

∵ In one minute amount of water removed is 40 gallons.

∴ In t minutes amount of water will be removed = 40t

So equation will be y = 40t

y = 40t is the equation which models the amount of water y in the pool after t minutes.

A and D are true.

Step-by-step explanation:

A) 80 × 10 = 800

B) 8 × 10 = 80, not 800

C) 800 × 10 = 8000, not 80

D) 8 × 10 = 80

E) 90 × 10 = 900, not 8
