Tiffany spent
35 of her money on 3 files and 8 foolscaps. The cost of one foolscap was thrice the cost of one file. She bought some more foolscaps with
13 of her remaining money. How many foolscaps did Tiffany buy altogether?
3 files and
8 foolscaps |
Remaining amount |
| 3x3 |
2x3 |
| |
More foolscaps |
Left |
| |
1x2 |
2x2 |
| 9 p |
2 p |
4 p |
Cost of 1 file = 1 u
Cost of 1 foolscap = 3 u
Cost of 3 files = 3 x 1 u = 3 u
Cost of 8 foolscaps = 8 x 3 u = 24 u
Total cost of 3 files and 8 foolscaps
= 3 u + 24 u
= 27 u
9 p = 27 u
1 p = 27 ÷ 9 = 3 u
Amount that Tiffany used to buy more foolscaps
= 2 p
= 2 x 3 u
= 6 u
Number of more foolscaps that Tiffany bought
= 6 u ÷ 3 u
= 2
Total number of foolscaps that Tiffany bought
= 8 + 2
= 10
Answer(s): 10
