Kathy spent
25 of her money on 6 folders and 5 punchers. The cost of one puncher was twice the cost of one folder. She bought some more punchers with
14 of her remaining money. How many punchers did Kathy buy altogether?

More punchers |
Left |
| |
1x3 |
3x3 |
| 8 p |
3 p |
9 p |
Cost of 1 folder = 1 u
Cost of 1 puncher = 2 u
Cost of 6 folders = 6 x 1 u = 6 u
Cost of 5 punchers = 5 x 2 u = 10 u
Total cost of 6 folders and 5 punchers
= 6 u + 10 u
= 16 u
8 p = 16 u
1 p = 16 ÷ 8 = 2 u
Amount that Kathy used to buy more punchers
= 3 p
= 3 x 2 u
= 6 u
Number of more punchers that Kathy bought
= 6 u ÷ 2 u
= 3
Total number of punchers that Kathy bought
= 5 + 3
= 8
Answer(s): 8
