Question

Eric made some bookmarks and keychains for sale. 2/5 of the items made were keychains. He sold 2/3 of the keychains and 48 bookmarks. He then had 1/3 of theĀ items left. How many items did Eric make at first?

Answer

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

Ans : 120 items.
