 Question 115309: A small company produces both doll houses and sets of doll furniture. The doll houses take 3 hours of labor to produce, and the furniture sets take 8 hours. The labor available is limited to 400 hours per week, and the total production capacity is 100 items per week. Existing orders require that at least 20 doll houses and 10 sets of furniture be produced per week. Write a system of inequalities representing this situation, where x is the number of doll houses and y is the number of furniture sets. Then graph the system of inequalities.

 Question 116010: This is not exactly what my problem is but it's the closest thing I could understand. The problem says "Coffee worth \$3.75 a pound was mixed with coffee worth \$4.35 a pound to produce a blend worth \$4.11 a pound. How much of each kind of coffee was used to produce 40 pounds of blended coffee?" My problem is finding the equations to solve by elimination because, this seems to need 3 variables in order to be made into the first equation. Hope I explained it well enough for you to help.
