Question

A factor 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 purple paint. Haw many drops of red and blue coloring will the factory need in the 50-gallon batch of purple paint?

Answer 1

• 1200 drops of red
• 800 drops of blue

Explanation:

There are 8 pints in 1 gallon, so 50×8 = 400 pints in 50 gallons.

400 × 3 red drops = 1200 red drops

400 × 2 blue drops = 800 blue drops
