<strong>Restaurant</strong> <strong>Receipts</strong> Algebra 2 HS Mathematics Unit: 05 Lesson: 01 Fill in or complete the information on this page as you work through the problem. What information is found on each receipt? Receipt A Receipt C Receipt B Receipt D What prices are possible for each item? List possible item prices Check—Do the prices work? What prices can be eliminated for certain items? Write the names of the items in the first column. Write the possible costs for each item in the top row. Eliminate possibilities by placing X’s in the appropriate boxes. ©2010, TESCCC 08/01/10 page 11 of 60
Systems of Equations Algebra 2 HS Mathematics Unit: 05 Lesson: 01 Using B for the cost of a burger, F for the cost of fries, N for the cost of nachos, and S for the cost of a soda, write equations for each statement below. 2 sodas and 3 burgers cost $18. 5 sodas and 6 burgers cost $39. 2 burgers, 2 fries, and 2 sodas cost $18. 2 nachos, 3 burgers, 2 fries, and 4 sodas cost $38. DEFINITION: DEFINITION: When used together, these form a ________________________ of equations, which is a set of two or more equations with two or more unknowns (or variables). The ________________________ to a system lists the values that can be used for each variable to make the equations in the system true (or, “check”). Samples: 1) 2x 3y 4z 3 x z 4 x 2y 3z 4 This is a _______ _____________ of equations because it uses _____ _________________ and has _____ ________________. Which of the following would be the solution to this system? A) x 4, y 1, z 2 B) x 9.5, y 0, z 5. 5 C) x 5, y 3, z 1 2) 2x 7y y 1 x 2 9 3 This is a _______ _____________ of equations because it uses _____ _________________ and has _____ ________________. Which ordered pair shows the solution to this system? A) (15, 3) B) (8, 1) C) (2, -2) Below, circle the correct solution to each equation. How can you determine the solution? 3) 4) 5x 3y 2z 16 y 3x 8 x y 5 z x 4y 1 8x 5y 3z 25 A) x 3, y 1 A) (1, -0.2, 5.8) B) x 7, y 29 B) (-2, 4, 7) C) x 7, y 9 C) (1, 1, 4) These answers are called “ordered triples” ©2010, TESCCC 08/01/10 page 13 of 60
