---------------------------------
Define x and y :
---------------------------------
Let x be the number of large boxes.
Let y be the number of smaller boxes.
---------------------------------
Construct equations :
---------------------------------
x + y = 125 -------------------------- (1)
50x + 30y = 4850 ---------------- (2)
---------------------------------
From equation (1) :
---------------------------------
x + y = 125
x = 125 - y
---------------------------------
Substitute x = 125 - y into (2) :
---------------------------------
50 (125 - y) + 30y = 4850
6250 - 50y + 30y = 4850
20y = 1400
y = 1400 ÷ 20
y = 70
---------------------------------
Sub y = 70 into equation 1
---------------------------------
x + y = 125
x + 70 = 125
x = 55
---------------------------------
Find the number of boxes :
---------------------------------
Large box = x = 55
Small box = y = 70
---------------------------------------------------------------------------------------------------
Answer: There are 55 large boxes and 70 small boxes.
