Question 84168: Three colors are mixed together in varying percentages. Each color has a different reflectance value. Reflectance values are Gray = 15%, Black =5% and White = 25%. The are mixed together in the following amounts Gray 35%, Black 15% and White 50% for a 100% total.
What is the reflectance average when the three different colors are mixed together in the listed percentage?
Color Reflectance Value Percent of Mix
Gray 15% 35%
Black 3% 15%
White 25% 50%

You can put this solution on YOUR website! Three colors are mixed together in varying percentages. Each color has a different reflectance value. Reflectance values are Gray = 15%, Black =5% and White = 25%. The are mixed together in the following amounts Gray 35%, Black 15% and White 50% for a 100% total.
What is the reflectance average when the three different colors are mixed together in the listed percentage?
Color Reflectance Value Percent of Mix
Gray 15% 35%
Black 3% 15%
White 25% 50%
:
Seems to be some contradiction in the Reflectance value of black, assume it is 5%
:
Treat it like a mixture problem, resulting amt = 100
Let x = reflectance value of resulting mixture:
:
.15(35) + .05(15) + .25(50) = x(100)
:
5.25 + .75 + 12.5 = 100x
:
18.5 = 100x
:
x = 18.5/100
:
x = .185 or 18.5%
