A local bakery sells cupcakes for $3 each and cookies for $2 each. If a customer buys a total of 15 items and spends $36, write a system of linear equations to find out how many cupcakes and cookies were purchased.

• x + y = 15, 3x + 2y = 36

• x + y = 10, 3x + 2y = 30

• x + y = 20, 3x + 2y = 40

• x + y = 15, 2x + 3y = 36
