Winnie spent
38 of her money on 4 correction tapes and 10 folders. The cost of one folder was twice the cost of one correction tape. She bought some more folders with
14 of her remaining money. How many folders did Winnie buy altogether?

| 3x4 |
5x4 |

Left |
| |
1x5 |
3x5 |
| 12 p |
5 p |
15 p |
Cost of 1 correction tape = 1 u
Cost of 1 folder = 2 u
Cost of 4 correction tapes = 4 x 1 u = 4 u
Cost of 10 folders = 10 x 2 u = 20 u
Total cost of 4 correction tapes and 10 folders
= 4 u + 20 u
= 24 u
12 p = 24 u
1 p = 24 ÷ 12 = 2 u
Amount that Winnie used to buy more folders
= 5 p
= 5 x 2 u
= 10 u
Number of more folders that Winnie bought
= 10 u ÷ 2 u
= 5
Total number of folders that Winnie bought
= 10 + 5
= 15
Answer(s): 15
