I am confused on this one

Problem #3: Toy Time! A manufacturer makes two toys: trucks and fire engines. There are four different departments used to manufacture these toys: .The sheet metal department requires 2 hours for each truck and 3 hours for each fire engine; with a total of 24,000 hours available each week. .The truck assembly department can handle at most 6600 trucks per week. .The fire engine assembly department can handle at most 5500 fire engines weekly. .The pointing department has a maximum capacity of 10,000 toys per week. The profit for each truck is $9.50 and for each fire engine is $14.00 Set up and solve a linear programming problem to find the maximum profit as well as the number of each toy that yields maximum profit
