A pencil at a stationery store costs $1, and a pen costs $1.50. Stefan spent $7 at the store. He bought a total of 6 items. Which system of equations can be used to find the number of pencils (x) and pens (y) he bought? (5 points)


x + 1.5y = 7
x + y = 6

1.5x + y = 7
x = 6y

x + 2y = 7
6x = 1.5y

2x + y = 7
6x = 1.5y
GPT 3.5
x + 1.5y = 7
x + y = 6

The system of equations that can be used to find the number of pencils (x) and pens (y) Stefan bought is x + 1.5y = 7 and x + y = 6.
