Question

a factory adds three red drops and two blue drops of coloring to white paint to make each pint of purple paint. the factory will make 50 gallons of this purple paint. how many drops of red and blue coloring will the factory need in the 50 gallon batch of purple paint?

Answer 1

1200 red drops and 800 blue drops.

First, find the number of pints of purple paint. There are 8 pints in each gallon, so multiply 50 times 8 to find that there are 400 pints.

Now, multiply the 400 pints times the number of drops of each color. 400 times 3 red drops is 1200 drops, and 400 times 2 blue drops is 800 blue drops.
