A store sells pencils for $0.50 each and erasers for $1. If a student bought a total of 20 items and spent $12, write a system of equations to find out how many pencils and erasers were purchased.

• x + 2y = 20 and 0.5x + y = 10

• x + y = 15 and 0.5x + 2y = 12

• The system of equations is: x + y = 20 and 0.5x + y = 12.

• 2x + y = 20 and 0.5x + 2y = 12
