Unit 5

Write the system and solving using a matrix.

33.  Julia’s Dance School sold a total of 320 tickets to the dance recital. They sold 98 more adult tickets than child tickets. Write a system of equations that could be used to determine the number of adult and child tickets sold.

34.  Jorge has to buy some shirts and pants for the upcoming school year. He has $300 to spend on $10 shirts and $15 pants. He would like to spend the same amount of money on shirts as pants. Write a system of equations that could be used to determine the number of shirts and pairs of pants he should buy.

35.  Mikey bakes cookies for the elementary school cookie sale. He has chocolate chip, oatmeal, and sugar cookies to sell. On the first day he earned $68 selling 12 dozen chocolate chip cookies and 8 dozen oatmeal cookie. The next day he only had sugar cookies and oatmeal cookies and made $56 selling 9 dozen oatmeal cookies and 10 dozen sugar cookies. Later that afternoon, he discovered he still had 3 dozen sugar cookies and sold them for $6. How much money did he make on the last day if he sold 7 dozen oatmeal cookies and 11 dozen chocolate chip cookies?

36.  Solve the system represented below.

37.  Write the Matrices for the system below.

-6r + 5s + 2t = -11

-2r + s + 4t = -9

4r – 5s + 5t = -4

Solve the systems of equations.

38.  x – 4y + 7z = 14 39. 3x + 2y + z = 3

3x + 8y – 2z = 13 x – 3y + z = 4
