Question

To make a shade of paint called jasper green, mix 4 quarts of green paint with 53 cups of black paint. Select an equation that calculates how quarts of green paint, , are mixed with a given amount of black paint, .

Answer 1

g = 12b /5

Explanation:

Given that:

Quarts of green paint = 4

Cup of black paint = 5/3

Quartz of green paint to be mixed with a given proportion of black paint.

Let proportion of black paint = b

Quartz of green paint = g

4 quartz = 5/3 cups

g quartz = b

Cross multiply :

4 * b = (5/3) * g

5/3 * g = 4b

g = 4b ÷ 5/3

g = 4b * 3/5

g = 12b /5
