The quantity of green paint needed to be mixed with 4 cups of black paint to make jasper green is 24 quarts
How much green paint should be mixed with 4 cups of black paint to make jasper green?
Convert quarts to cups
1 quarts = 4 cups
4 quarts = 16 cups
Mixture A for jasper green:
Green paint = 4 quarts = 16 cups
Black paint = 2/3 cups
Mixture B for jasper green:
Green paint = x cups
Black paint = 4 cups
Set up the proportion
16 : 2/3 = x : 4
16 ÷ 2/3 = x / 4
16 × 3/2 = x/4
48/2 = x/4
cross product
48 × 4 = 2 × x
192 = 2x
Divide both sides by 2
x = 192/2
x = 96 cups
Therefore, 96 cups converted to quarts is
96/4
= 24 quarts
