1,3 f(n,p)=100n+350p+500 (n=number non-peak hrs, p=number peak hrs) It costs $100 to air a commercial during off-peak hours on the radio and $350 during peak hours. A company charges $500 to make the commercial. Write a model for the total amount that will be spent making and airing the commercial as a function of the number of times it is aired during off-peak and peak hours.

2,2 25 tourist seats Fly-High Airlines sells business class and tourist class seats for its charter flights. To charter a plane at least 5 business class tickets must be sold and at least 9 tourist class tickets must be sold. The plane does not hold more than 30 passengers. Fly-High makes $40 profit for each business class ticket sold and $45 profit for each tourist class ticket sold. In order for Fly- High Airlines to maximize its profits, how many tourist class seats should they sell?

2,3 Plane 550 mph, wind 50 mph An airplane flying into a head wind travels the 1800-mile flying distance between two cities in 3 hours and 36 minutes. On the return flight (with a tail wind), the same distance is traveled in 3 hours. Find the ground speed of the plane and the speed of the wind, assuming that both remain constant.

10
2,4 A plane has x-intercept of 4, y-intercept of -5, and z-intercept of -3. If you were to write the equation of this plane in standard form, what would be the value of d? The LCM of 4,-5,-3, which is 60

11
3,1 Write the equation of the parabola through (-1,-17), (0,-14), and (2,10). y=3x^2+6x-14

12
3,2 Sell 6 small sheds Bob builds tool sheds. He uses 10 sheets of dry wall and 15 studs for a small shed and 15 sheets of dry wall and 45 studs for a large shed. He has available 60 sheets of dry wall and 135 studs. If Bob makes $390 profit on a small shed and $520 on a large shed, how many of each type of building should Bob build to maximize his profit?

13
3,3 DAILY DOUBLE! A pharmacist needs 8 oz of a 50% saline solution. How many ounces of 60% saline solution and 20% saline solution must he use? 6 oz of 60% and 2 oz of 20%

14
3,4 NON-MATH QUESTION! What was the original name for Mario in the 1981 arcade game Donkey Kong? Jumpman

15
4,1 Describe the solutions to the system in terms of x: Points of the form (x,3-x,6x-11)

16
4,2 Trivia Who is known as the Father of Linear Programming? George Dantzig

17
4,3 At store A, cameras are available for 15% off. At store B, there is a $300 coupon for all cameras. Assume the lowest priced camera is $700. When does Store A have a better deal? If the price is over $2000

18
4,4 (0,0,0) is always a solution If a linear system has the form ax+by+cz=0 dx+ey+fz=0 gx+hy+kz=0 it is called homogeneous. Explain why any homogeneous system has at least one solution.
