Question

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?

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

Answer 3

x = # of pencils
y = # of pens

he bought 6 items (pens & pencils) so what equation can we form?

(number of pencils) + (number of pens) = total number of items

Answer 7

use that template

Answer 8

so 6+6 @jim_thompson5910

6x + 6=y

Answer 12

no, it should be x+y = 6

Answer 13

you might be thinking of something else?

Answer 14

sorry
i can end o be slow at times

Answer 15

tend*

Answer 16

that's ok

Answer 17

okay So the equation will be x + y =6

Answer 18

yes

Answer 19

that's one of the equations in the system

Answer 20

ok i think i have the other one so im guessing my answer will be A @jim_thompson5910
