Answer 1

y = 12x represents the gallons of paint used in x hours.

Step-by-step explanation:

CJ uses 3 gallons of paint in 15 minutes,

15 minutes = 3 gallons

1 minutes = $\frac{3}{15} = \frac{1}{5} \ gallons$

1 hour = 60 minutes

Gallons of paint used in 1 hour;

1 hour = $\frac{1}{5}*60=12\ gallons$

CJ uses 12 gallons of paint in 1 hour.

For x hours = 12*x = 12x

Gallons of paints used = y

y = 12x represents the gallons of paint used in x hours.
