A florist charges for flower arrangements based on the number of each type of flower in the arrangement. Different types of flowers have different costs. An arrangement of 12 carnations and 12 roses cost $60. An arrangement of 16 carnations and 8 roses cost $52. The system shown can be used to determine the cost of each carnation, x, and rose, y. { 12x + 12y = 60 { 16x + 8y = 52 Which graph correctly represents the system and correctly labels the point, or points, which represents the solution for how much each type of flower costs?

• Graph A

• Graph B

Lenwood has $150 to spend on a barbecue. He plans to buy chicken at $2.50 per pound and ribs at $6.50 per pound. Which equation represents the constraints on his purchase of c pounds of chicken and r pounds of ribs?

• 2.50c + 6.50r = 150

• 2.50c + 6.50r = 150 – 6.50 – 2.50

• (6.50 + 2.50) (c + r) = 150

• (6.50 – 2.50) (c + r) = 150 – 6.50 – 2.50
