Mr. Kelly buys a total of 40 boxes of pens and pencils for his class. Each box of pens costs $5 . Each box of pencils costs $2 . Mr. Kelly spends a total of $131 on the pens and pencils. Which equations form a system of equations that can be used to determine the number of boxes of pens, x , and the number of boxes of pencils, y , that Mr. Kelly buys? Select two correct answers.

• x + y = 40

• x + y = 131

• 5x + 2y = 40

• 5x + 2y = 131

• 2x + 5y = 131
