Question

there is a mixture of 20% red paint, 35% yellow paint, and 45% water. If 5 quarts of red paint are added to 20 quarts of the mix, what is the percentage of red paint in the new mixture?

Answer 1

How many total quarts in the original mixture?

Answer 2

20 quarts?

Answer 3

20% of 20 = 4 quarts of red originally
add 5 quarts now you have 9 quarts of red in the total mix of (20 + 5 )
as a percentage = 9/25* 100 = 36 %

Answer 4

check 9/25 + 7/25 + 9/25 = 25/25
red , yellow and water respectively
36% + 28% + 36% = 100%
