Explanation Given Information: The price quoted is $3000 per spot for The Big Bang Theory and $1000 for American Dad. The budget is of $12000. No more than 50% of the advertisements will occur on the American Dad. Formula used: The steps for Linear Programming problems: 1. To make the corner points are inside the rectangle draw a rectangle large enough. 2. Shade the outside of the rectangle so that a new bounded feasible region can be defined and locate the new corner points. 3. Obtain the optimal solutions by the use of bounded feasible region. 4. If the optimal solution occurs at the one of the corner points, then only LP problem has that corner point as the optimal solution otherwise it has no optimal solution. Calculation: Consider the number of spots of The Big Bang Theory to be x and consider the number of spots of American Dad to be y. So, according to given data, x + y ≥ 30 3000 x + 1000 y = 120000 − x + y ≤ 0 The constraints include that x ≥ 0 , y ≥ 0 because number of spots of The Big Bang Theory and number of spots of American Dad cannot be negative. Maximize exposure E = 1.8 x + 1.5 y subject to the given following constraints x + y ≥ 30 , 3000 x + 1000 y ≤ 120000 , − x + y = 0 and x ≥ 0 , y ≥ 0 . Consider the first constraint equation. x + y = 30 Isolate the variable y , by subtracting x from both sides, x − x + y = 30 − x y = 30 − x To plot the graph of the function, find the ordered pairs of the first constraint equation by substituting different values of x . For x = 0 , substitute 0 for x , y = 30 − x = 30 − x For x = 10 , substitute 10 for x , y = 30 − 10 = 20 For x = 20 , substitute 20 for x , y = 30 − 20 = 10 Construct a table for the ordered pairs of first constraint equation, x 0 10 20 y 30 20 10 Test the first inequality by ( 0 , 0 ) test coordinates. x + y ≥ 30 0 + 0 ≥ ? 30 0 + 0 ≥ ? 30 0 ≥ 30 The inequality is not satisfied. If the test point does not satisfy the inequality then the set of solutions is the line plus the entire region on the other side of the line i.e. away from the test coordinate ( 0 , 0 ) . Consider the second constraint equation, 3 x + y = 120 Isolate the variable y , by subtracting x from both sides, 3 x − 3 x + y = 120 − 3 x y = 120 − 3 x To plot the graph of the function, find the ordered pairs of the second constraint equation by substituting different values of x . For x = 0 , substitute 0 for x , y = 120 − 3 ⋅ 0 = 120 − 0 = 120 For x = 20 , substitute 20 for x , y = 120 − 3 ⋅ 20 = 120 − 60 = 60 For x = 40 , substitute 40 for x , y = 120 − 3 ⋅ 40 = 120 − 120 = 0 Construct a table for the ordered pairs, x 0 20 40 y 120 60 0 Test the second inequality by ( 1 , 1 ) test coordinates. 3 x + y ≤ 120 3 ⋅ 0 + 0 ≤ ? 120 0 + 0 ≤ ? 120 0 < 120 The inequality is satisfied. If the test point satisfies the inequality then the set of solutions is the line plus the entire region on the same side of the line as the test coordinate ( 1 , 1 )

Page I of 3 Date: Making a Profit At Elsenhower High School's home games, booster clubs willl often hold raffles to raise money for the for special causes. The Girls' Basketball Team had a gift basket filled with movie items to be Tamed off at the Coaches Versus Cancer night. The girls decided to charge $2 a raffle ticket. The gift basket contained: 4 tickets which cost $10.25 each, 12 boxes of candy which cost $2.50 each, a box of popcorn which costs $12, and 4 pairs of 3-D glasses which cost $4.25 each. Revenue is the amount of money the girls' basketball team brings in - its income. In this case, revenue is a function of number of tickets sold. Let x be the number of tickets sold. What is the revenue function? a. Revenue = f(x) = Cost is how much money the girls' basketball team spent. In this situation, cost is a constant function. What is the cost function? [Hint: The cost function equals the expenses.] b. Cost = Profit = Revenue – Cost. What is the profit function? (Use the…

Farm Fact #3: In 2007, Massachusetts maple producers set 230,000 taps to collect sap, which, after boiling produced 30,000 gallons of maple syrup. It takes about 40 gallons of sap to produce one gallon of syrup." And "Suppose the sap is collected in gallon buckets that hang under each tap, and the maple season lasts one month? And "Read the label of a "pancake syrup" bottle to find out how much maple syru it contains." How many gallons of syrup did each tap yleld? How many gallons of sap did each tap yield? What extra information would you need ot estimate the number of sugar maple trees that were tapped? How many times a day (how often) will the buckets of sap need to be emptled? (What fraction of a bottle of generic "pancake syrup" is pure maple syrup?) What fraction of the cost of generic "pancake syrup" can you attribute to the cost of pure maple syrup?

A ticket between Corellia and Dantooine (located in a galaxy far far away) sells for $150. The plane can hold 100 people. It costs $8000 to fly an empty plane. Each person on the plane incurs variable costs of $30 (for food and fuel). If the flight is overbooked, anyone who cannot get a seat receives $300 in compensation. On average, 95% of all people who have a reservation show up for the flight. To maximize profit, how many reservations for the flight should you book? Hint: You can assume that the number of people that show up for a flight follows a binomial random variable.
