Problem Solving  A manufacturer of cell phones makes a profit of $25 on a deluxe model and $30 on a standard model. The company wishes to produce at least 80 deluxe models and at least 100 standard models per day. To maintain high quality, the daily production should not exceed 200 phones. How many of each type should be produced daily in order to maximize the profit? HOW DO I WRITE THE CONSTRAINTS TO GRAPH A FEASIBLE REGION?

deluxe model  x
standard model  y
x ≥ 80
y ≥ 100
x+y < 200
Profit = 25x + 30y
