**Reiny**, Tuesday, December 2, 2008 at 8:31pmI will assume that each of the 11 students bought either one cookie or one brownie.

let the number of cookies be c

then the number of brownies is 11-c

solve this equation:

40c + 50(11-c) = 510

(let me know if you don't get cookies =4

brownies = 7 ?)
