Gem spent
25 of her money on 8 markers and 6 notebooks. The cost of one notebook was four times the cost of one marker. She bought some more notebooks with
16 of her remaining money. How many notebooks did Gem buy altogether?

1 p |
5 p |
Cost of 1 marker = 1 u
Cost of 1 notebook = 4 u
Cost of 8 markers = 8 x 1 u = 8 u
Cost of 6 notebooks = 6 x 4 u = 24 u
Total cost of 8 markers and 6 notebooks
= 8 u + 24 u
= 32 u
4 p = 32 u
1 p = 32 ÷ 4 = 8 u
Amount that Gem used to buy more notebooks
= 1 p
= 1 x 8 u
= 8 u
Number of more notebooks that Gem bought
= 8 u ÷ 4 u
= 2
Total number of notebooks that Gem bought
= 6 + 2
= 8
Answer(s): 8
