Irene spent
35 of her money on 6 folders and 10 glues. The cost of one glue was thrice the cost of one folder. She bought some more glues with
14 of her remaining money. How many glues did Irene buy altogether?

| 6 p |
1 p |
3 p |
Cost of 1 folder = 1 u
Cost of 1 glue = 3 u
Cost of 6 folders = 6 x 1 u = 6 u
Cost of 10 glues = 10 x 3 u = 30 u
Total cost of 6 folders and 10 glues
= 6 u + 30 u
= 36 u
6 p = 36 u
1 p = 36 ÷ 6 = 6 u
Amount that Irene used to buy more glues
= 1 p
= 1 x 6 u
= 6 u
Number of more glues that Irene bought
= 6 u ÷ 3 u
= 2
Total number of glues that Irene bought
= 10 + 2
= 12
Answer(s): 12
