8 p |
3 p |
9 p |
Cost of 1 folder = 1 u
Cost of 1 correction tape = 4 u
Cost of 8 folders = 8 x 1 u = 8 u
Cost of 6 correction tapes = 6 x 4 u = 24 u
Total cost of 8 folders and 6 correction tapes
= 8 u + 24 u
= 32 u
8 p = 32 u
1 p = 32 ÷ 8 = 4 u
Amount that Roshel used to buy more correction tapes
= 3 p
= 3 x 4 u
= 12 u
Number of more correction tapes that Roshel bought
= 12 u ÷ 4 u
= 3
Total number of correction tapes that Roshel bought
= 6 + 3
= 9
