A pencil at a stationery store costs $1, and a pen costs $1.50. Shawn spent $12 at the store. He bought a total of 9 items. Which system of equations can be used to find the number of pencils (x) and pens (y) he bought? 1.5x + y = 12 x = 9y x + 1.5y = 12 x + y = 9 x + 9y = 12 x = 1.5y 9x + y = 12 x = 1.5y

so you're supposed to have 1x + 1.50y =12
hysusonic
  • hysusonic
that's how much he spent and how many items he bought would be x+y=9

no... A is saying that a pencil costs $1.50 when a pencil costs $1

1.5x + y = 12 x = 9y x + 1.5y = 12 x + y = 9 x + 9y = 12 x = 1.5y 9x + y = 12 x = 1.5y
