Victoria spent
37 of her money on 9 punchers and 6 glues. The cost of one glue was thrice the cost of one puncher. She bought some more glues with
16 of her remaining money. How many glues did Victoria buy altogether?

6 glues |
Remaining amount |
| 3x3 |
4x3 |

More glues |
Left |
| |
1x2 |
5x2 |
| 9 p |
2 p |
10 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 6 glues = 6 x 3 u = 18 u
Total cost of 9 punchers and 6 glues
= 9 u + 18 u
= 27 u
9 p = 27 u
1 p = 27 ÷ 9 = 3 u
Amount that Victoria used to buy more glues
= 2 p
= 2 x 3 u
= 6 u
Number of more glues that Victoria bought
= 6 u ÷ 3 u
= 2
Total number of glues that Victoria bought
= 6 + 2
= 8
Answer(s): 8
