Gillian spent
35 of her money on 9 punchers and 3 glues. The cost of one glue was thrice the cost of one puncher. She bought some more glues with
14 of her remaining money. How many glues did Gillian buy altogether?

1x1 |
3x1 |
| 6 p |
1 p |
3 p |
Cost of 1 puncher = 1 u
Cost of 1 glue = 3 u
Cost of 9 punchers = 9 x 1 u = 9 u
Cost of 3 glues = 3 x 3 u = 9 u
Total cost of 9 punchers and 3 glues
= 9 u + 9 u
= 18 u
6 p = 18 u
1 p = 18 ÷ 6 = 3 u
Amount that Gillian used to buy more glues
= 1 p
= 1 x 3 u
= 3 u
Number of more glues that Gillian bought
= 3 u ÷ 3 u
= 1
Total number of glues that Gillian bought
= 3 + 1
= 4
Answer(s): 4
