Question 368601: Here is my problem that I am stuck with and do not know how to finish: The problem is on Systems of Linear Equations; Matrices. The problem is: As the restaurant owern there are many decisions that you need to make on a daily basis, such as wher to keep inventory levels. You wish to replenish our stock of dishes by purchasing 250 sets for your restaurant. You have two dish design from which to choose. 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 offer
Hint: Let x = the number of sets of $20 dishes and y = the number of sets of $45 dishes. Solve the equations for the different dish designs to be ordered with the desired technique: graphing, substitution, elimination matrix. Explain how to check your solution for both equations. This is as far as I got because I really don't understand it. x = $20, y = $45, total of 250, x + y = 250, $20x + 45y = $6,800 My email address is nifty_at_fifty57@yahoo.com Thank you
