TJ and Meredith go to the movies. TJ buys one soda and three bags of candy and spent $11.25. Meredith buys one soda and one bag of candy and spent $6.25. Write a system of equations to model the situation.

• x + 3y = 11.25

  x + y = 6.25

• y = 3x + 11.25

  y = x + 6.25

• x + y = 3

  11.25x + 6.25y = 17.5

• x - y = 6.25

  x - 3y = 11.25

TJ and Meredith go to the movies. TJ buys one soda and three bags of candy and spent $11.25. Meredith buys one soda and one bag of candy and spent $6.25. Solve the system to determine the price of a soda and the price of a bag of candy.

• a soda cost $3.75

  a bag of candy cost $2.50

• a soda cost $2.50

  a bag of candy cost $3.75

• a soda cost $2

  a bag of candy cost $1

• a soda cost $11.25

  a bag of candy cost $6.25
