Sara is selling cookies and brownies for a fundraiser for the school band. She charges $2.25 for 2 cookies and 1 brownie. She charges $5.75 for 4 cookies and 3 brownies. How much does sara charge per cookie? how much per brownie?

cookies = x

brownies = y

2x + y = 2.25
y = 2.25 - 2x
4x +3y = 5.75

its $0.50 per cookie and $1.25 per brownie
