At a restaurant, glasses are stored in two different sized boxes. One box contains 12 glasses and teh other contains 16 glasses. If the average number of glasses per box is 15, and there are 16 more of the larger boxes what is the total number of glasses at the restaurant? (Assume tha all boxes are filled to capacity)

pls show full working...thanks

Given 12n + 16(n+16) = 15(2n+16) = x, find x

16*16 = 2n + 16*15, or n = 8, or x = 480
