Suppose you are making mosaic tiles from 3 types of stained glass. You need 6 square feet of glass for the project and you want there to be as much iridescent glass as red and blue glass combined. The cost of a sheet of glass having an area of 0.75 square foot is .50 for iridescent, .50 for red, and .50 for blue. How many sheets of each type should you purchase if you plan to spend on the project?
I don’t understand this. Can anyone help?
