Question

a bake sale and pep squad is selling cookies. On one ticket they sold two chocolate chip cookies and five oatmeal cookies for $21. On another ticket they sold three chocolate chip cookies and three oatmeal cookies for $18.

Which system of equations below can be used to determine the price of a chocolate chip cookie and the price of an oatmeal cookie?

Let x represent the cost of a chocolate chip cookie, and let y represent the cost of an oatmeal cookie.
5x + 8y = 39
5x - 8y = 39

2x + 5y = 21
3x + 3y = 18

2x + 3x = 15
5y + 3y = 24

2x + 3y = 21
5x + 3y = 18
