Reiny
number of cookies ---- x
number of brownies ----- y
x + y = 10 ----> y = 10-x
1.25x + 2.5(10-x) = 20
now just solve for x and after that you can get y from y = 10-x
number of brownies ----- y
x + y = 10 ----> y = 10-x
1.25x + 2.5(10-x) = 20
now just solve for x and after that you can get y from y = 10-x
