To get the answer we can use proportion
8 ginger ----------------- 3 fruit
12 ginger ----------------x
Crossmultiply now
8x=12*3 /:8
x=

x=<u />

To not change ratio we have to have 4.5 cups of fruilt juice. We initialy had 3, so we have to add 1.5 cup of fruit juice.
convert the feet to inches
1 foot = 12 inches
so 1.5 ft =1.5*12 = 18 inches
now multiply all 3
14*18*7 = 1764 cubic inches
This will generate a line quickly dropping from left to right, with an x-intercept of 0.4 and a y-intercept of 2.

Answer:
Pete's: 
Carla's: 
Step-by-step explanation:
Let's assume that
is the amount of rooms painted, and 
For Pete's Painting Company, they charge a flat fee of $60, so we will have a constant of 60.

, the amount of rooms painted.
This gets us the function 
For Carla's Creative Colors, they charge 20$ to hire the workers, meaning this will be our constant.
They also charge $40 a room, meaning we will multiply 40 by
, the amount of rooms painted.
So the function is
