On average raise students math grades by 10%
L = large box S = small box
8L + 3S = 166 Eq (1)
2L + 5S = 67 Eq (2)
The above equations were obtained because it said a certain number of large and small boxes equaled to a certain weight. From there use substitution or elimination to solve the system of equations. You want to solve for "L" to find the weight of the large box and "S" for the small box. Good luck!
