i am really confused on how to do this
What you have here is a classic proportion problem. We have 5oz. of orange tint for every 3 quarts of white.
5oz O:3qt W
We are told we will be mixing with 6 Gallons of White. This is a different unit of measure. We must now convert our gallon units to quarts.
1 Gallon = 4 Quarts therefore,
6 Gallon= 24 Quarts
We now know we have 24 quarts of white paint. Because we know we must mix 5oz of orange tint for every 3 quarts we must mix 8x 5oz or 40 oz of tint
