jill has a hot tub that holds 1,260 gallons of water. she needs to drain the hot tub, so that it can be moved to a new location in her backyard. if draining the hot tub is modeled by the equation y = -793/2 x + 1,260, how long will it take to drain the hot tub?

a) 2 hours 48 minutes
b) 2 hours 59 minutes
c) 3 hours 11 minutes
d) 3 hours 22 minutes

C)3 hours 11 minutes

Step-by-step explanation:

We are given that  Jill has a hot tub that holds 1,260 gallons of water.

Draining the hot tub is modeled by the equation :

Now we are asked to find how long will it take to drain the hot tub

So, substitute y = 0 in equation :

So, it will take 3.17780580076 hours

Now 1 hour = 60 minutes

So, 0.17780580076 hours =

                                            = minutes

                                            ≈ 11 minutes

So, it will take 3 hours and 11 minutes    

Hence it will take 3 hours and 11 minutes to drain the hot tub .
