A family is coloring eggs and wants to make two shades of purple, “light purple” and “deep purple”. They have 30 tablespoons of red solution and 2 tablespoons of blue solution. If “light purple” consists of 2% blue solution, and “deep purple” consists of 10% blue solution, how much of each version of purple solution can be created? Let x represent thenumber of tablespoons of “light purple” to be created, and let y represent the number of tablespoons of “deep purple”. Based on the information provided, the two tablespoons of blue solution will be distributed according to the following linear equation. 2 = ? x + ? y Complete the equation above by filling in the boxes, then write a similar linear equation that shows the distribution of the red solution. Solve the resulting system of linear equations.
