Game shop

Game shop

A linear programming Application


The setup

The setup

  • You are the new owner of a game shop in Queen Creek. The previous owner is now programming drones for the NSA to secretly monitor Apache Junction flash mobs. Your first duty as new owner and store manager is to create an advertising plan based on the budget available. You must figure out how many radio and TV ads to purchase

    • Radio ads cost $600 per airing.

    • TV ads cost $1200 per airing.

    • You total advertising budget is $9,000.


Constraint 1

Constraint 1

  • If we let x = radio ads and y = TV ads, write an inequality for our advertising budget.


Constraint 11

Constraint 1

  • If we let x = radio ads and y = TV ads, write an inequality for our advertising budget.

    • It costs 600 for each radio add, so our radio ad cost is 300x


Constraint 12

Constraint 1

  • If we let x = radio ads and y = TV ads, write an inequality for our advertising budget.

    • It costs 600 for each radio ad, so our radio ad cost is 300x

    • It costs 1200 for each TV ad, so our TV ad cost is 600y


Constraint 13

Constraint 1

  • If we let x = radio ads and y = TV ads, write an inequality for our advertising budget.

    • It costs 600 for each radio ad, so our radio ad cost is 300x

    • It costs 1200 for each TV ad, so our TV ad cost is 600y

    • Our total budget is 9000, so our ad costs have to be less than or equal to that.


Constraint 2

Constraint 2

  • The television station called to say that we are only allowed to purchase up to 6 TV ads on their Saturday morning gaming retrospective. Write an inequality for this constraint.


Constraint 21

Constraint 2

  • The television station called to say that we are only allowed to purchase up to 6 TV ads on their Saturday morning gaming retrospective. Write an inequality for this constraint.


Constraint 3

Constraint 3

  • The radio station has informed us that their DJ threatened to quit if he had to listen to more than one add from a game shop per show. They are limiting us to 7 radio ads. Write an inequality for this constraint.


Constraint 31

Constraint 3

  • The radio station has informed us that their DJ threatened to quit if he had to listen to more than one add from a game shop per show. They are limiting us to 7 radio ads. Write an inequality for this constraint.


Constraint 4

Constraint 4

  • It is impossible to buy a negative number of TV ads. Write an inequality for this constraint.


Constraint 41

Constraint 4

  • It is impossible to buy a negative number of TV ads. Write an inequality for this constraint.


Constraint 5

Constraint 5

  • It is impossible to buy a negative number of radio ads. Write an inequality for this constraint.


Constraint 51

Constraint 5

  • It is impossible to buy a negative number of radio ads. Write an inequality for this constraint.

Objective function

OBJECTIVE FUNCTION

  • Write an objective function for game sales. (Hint: Think about how each TV and radio ad affects sales.)


Objective function1

OBJECTIVE FUNCTION

  • Write an objective function for game sales. (Hint: Think about how each TV and radio ad affects sales.)

    • f(x, y) = 150x + 100y


Objective function2

OBJECTIVE FUNCTION

  • Write an objective function for game sales. (Hint: Think about how each TV and radio ad affects sales.)

    • f(x, y) = 150x + 100y

  • Substitute the coordinates of the vertices into the objective function.


Objective function3

OBJECTIVE FUNCTION

  • Write an objective function for game sales. (Hint: Think about how each TV and radio ad affects sales.)

    • f(x, y) = 150x + 100y

  • Substitute the coordinates of the vertices into the objective function.
