You can put this solution on YOUR website! ---
x = number of chocolates
y = price per item
---
xy = 120
(x + 2)(0.80y) = 120
---
xy = 120
0.80xy + 1.6y = 120
0.80(120) + 1.6y = 120
1.6y = 120 - 0.80(120)
y = 0.20*(120)/1.6
y = 15
---
answer:
x = number of chocolates = 120/15 = 8
y = price per item = 15 Tk.
