Question

A factory adds 3 red drops and 2 blue drops of coloring to white paint to make each pint of purple paint. The factory will make 50 gallons of the purple paint.How many drops of red and blue coloring will the factory need in the 50 gallon batch of purple paint.

Answer 1

Number of red and blue drops to make purple paint are 1200 and 800.

Explanation:

We are given that,

The total amount of the purple paint is 50 gallons.

As, 1 gallon = 8 pints.

So, 50 gallons = 50 × 8 = 400 pints.

Since, we have,

The number of red drops to make 1 pint of the purple paint = 3

Then, number of red drops to make 400 pints of purple paint = 400 × 3 = 1200

Also, The number of blue drops to make 1 pint of the purple paint = 2

Then, number of blue drops to make 400 pints of purple paint = 400 × 2 = 800

Hence, the number of red and blue drops to make purple paint are 1200 and 800.
