1x1 |
5x1 |
| 4 p |
1 p |
5 p |
Cost of 1 correction tape = 1 u
Cost of 1 folder = 2 u
Cost of 2 correction tapes = 2 x 1 u = 2 u
Cost of 3 folders = 3 x 2 u = 6 u
Total cost of 2 correction tapes and 3 folders
= 2 u + 6 u
= 8 u
4 p = 8 u
1 p = 8 ÷ 4 = 2 u
Amount that Tina used to buy more folders
= 1 p
= 1 x 2 u
= 2 u
Number of more folders that Tina bought
= 2 u ÷ 2 u
= 1
Total number of folders that Tina bought
= 3 + 1
= 4
Answer(s): 4
