Question 252153: As a restaurant owner there are many decisions that you need to make on a daily basis, such as inventory levels. You wish to replenish your stock of dishes by purchasing 250 sets for your restaurant. You have available two different dish designs. One design costs $20 per set and the other $45 per set. If you only have $6,800 to spend, how many of each design should you order? Hint: Let x = the number of $20 dishes and y = the number of $45 dishes.

x+y=250
20x+45y=6800
.
y=250-x
20x+45(250-x)=6800
20x+11250-45x=6800
-25x=-4450
x=178
y=72
