2 Your parents gave you their credit card to go buy a new outfit. You went to the mall and bought a total of 15 items. You only purchased pants and shirts. Pants cost $45 each and shirts cost $32 each. Your total bill was $558. a) How many shirts and pairs of pants did you buy? b) For how long will you be grounded?

3 1. Define the variables 2. Set up two equations 3. Solve using elimination 4. State your solution in a complete sentence. 5. Check your solution.

4 System 1: will be X + Y = total number of things System 2: will be costX + costY = Total money

5 1. You sell tickets for admission to your school play and collect a total of $104. Admission prices are $6 for adults and $4 for children. You sold 21 tickets. How many adult tickets and how many children tickets did you sell?

6 Define variables: System of equations: State your solution(s): Solve A = # of Adult Tickets C= # of Children’s Tickets A + C = 21 6A + 4C = 104

7 2. Your family goes to a restaurant for dinner. There are 6 people in your family. Some order the chicken dinner for $14.80 and some order the steak dinner for $17. If the total bill was $91, how many people ordered each type of dinner?

8 Define variables: System of equations: State your solution(s): Solve H = # Steak Dinners C = # of Chicken Dinners H + C = 6 14.80C + 17H = 91

9 POST-IT CHECK: You are selling hamburgers and corndogs at the concession stand. The hamburgers cost $3.50 and the corndogs cost $1.50. The concession stand collects $1300 in sales and determines there were a total of 600 items were sold. How many hamburgers were sold?

10 System 1: will be costX + costY = Cost of First System 2: will be costX + costY = Cost of Second

11 4. Casey orders 3 pizzas and 2 orders of breadsticks for a total of $29.50. Rachel orders 2 pizzas and 3 orders of breadsticks for a total of $23. How much does a pizza cost

12 Define variables: System of equations: State your solution(s): Solve P = cost PIZZA B = cost OF bread sticks 3P + 2B = 29.50 2P + 3B = 23

13 POST –IT CHECK: At an Italian bistro, the costs of 2 plates of spaghetti and 1 salad is $27.50. The cost for 4 plates of spaghetti and 3 salads is $59.50. Find the cost of a plate of spaghetti and a salad.

14 Extra Example: You are going to Disney World! The hotel is offering two different vacation packages. Plan A has 3 nights in the hotel and 2 tickets to Disney World for $580. Plan B has 5 nights in the hotel with 3 tickets to Disney World for $945. What is the cost of each night in the hotel and each ticket?

15 Define variables: System of equations: State your solution(s): Solve N = Nights at hotel T = Tickets to Disney 3N + 2T = 580 5N + 5T = 945 N = 150 T = 65 Each night at the hotel costs $150 and each ticket to Disney costs $65.

16 Closing: NONE Finish classwork. TOD Homework: Textbook pp. 151 – 152 (10, 20, 21, 30)
