Answer:

40 gallons

Explanation:

Let the number of gallons that would completely fill the bathtub be represented by N.

Since 12 gallons of water gives 30% of the number of gallons to fill the bathtub, then;

30% of N = 12


(30)/(100) x N = 12

30N = 12 x 100

30N = 1200

divide both sides by 30,

N =
(1200)/(30)

= 40

The number of gallons that would completely fill the bathtub is 40 gallons.
