Question

I am horrible with this kind of stuff:

There are 4 pints of green paint in a gallon bucket. The paint is made from equal amounts of yellow paint and blue paint. To create a different shade of green, the mixture needs to be 80% yellow. How many pints of yellow paint need to be added to the bucket to make the mixture 80% yellow?

Brandon says to get that shade of green, 6 pints of yellow paint need to be added to the bucket. Bianca says that won't work. In two or more complete sentences, explain who is correct and why. In your explanation, include the calculations to support the correct answer.

Answer 1

There are 2 pints of blue and 2 pints of yellow in the bucket to start. You must add enough yellow paint so that the 2 pints of blue is 20% of the total . That is you need 8 pints of yellow mixed with the 2 pints of blue. There are 2 pints of yellow there already so you need to add 6 pints of yellow as Brandon says. Brandon is right.

Answer 2

Oh that make sense thank you.
