Question

Answer

Eric made some bookmarks and keychains for sale. 2/5…

total items at first ——- 15u
key chains ——- 6u
(2/3) x 6u = 4u
6u – 4u = 2u
bookmarks ——- 9u
9u – 48

2u + 9u – 48 = 11u – 48 ——- (1/3) x (15u) = 5u
11u – 5u = 6u ——- 48
1u ——- 48/6 = 8
15u ——- 8 x 15 = 120

Let’s try the ratio way.

Keychains      :  Bookmarks   :

Total

2                      : 3                       :  5
X3 X3 X3
6                      : 9                       : 15 

After sales

Keychains Bookmarks Total
2 (Left 1/3) 3 ( 5 – 2, Total – Keychains)  5 (Left 1/3 of beginning)

He sold 48 bookmarks,
9u-3u = 48
6u = 48
u = 8

In the beginning he made 15u = 15X 8 = 120 ###
