Solve by elimination.
Rachel has started a small company making organic honey. She makes large and small containers. She has found the costs of running her business to have a linear relationship which can be 5.5x + 7.5y = 930. She wants to sell a small container for 12 dollars and a larger container for 15 dollars and earn 1920 dollars. That creates a linear relationship modeled by 12x + 15y = 1920. How many of each kind of organic honey containers should she sell to fulfill her revenue and cost projections? (Hint: 7.5 * -2 = -15)
