A pencil at a stationery store costs $1, and a pen costs $1.50. Stella spent $21 at the store. She bought a total of 18 items. Which system of equations can be used to find the number of pencils (x) and pens (y) she bought?
x + 18y = 21
x = 1.5y
18x + y = 21
x = 1.5y
x + 1.5y = 21
x + y = 18
1.5x + y = 21
x = 18y
