a pump removes 1000 gal of water from a pool at a constant rate of 50 gal/min. which equation models the amount of water y in the pool after t minutes?
d) y= -50t + 1000 You can re-arrange as The amount of water left in the pool Y = 1000 gal at the beginning minus 50 gal x number of minutes passed. 1000 - 50t (or -50t+1000)
