Cost of 1 puncher = 1 u
Cost of 1 foolscap = 4 u
Cost of 4 punchers = 4 x 1 u = 4 u
Cost of 8 foolscaps = 8 x 4 u = 32 u
Total cost of 4 punchers and 8 foolscaps
= 4 u + 32 u
= 36 u
9 p = 36 u
1 p = 36 ÷ 9 = 4 u
Amount that Jaslyn used to buy more foolscaps
= 4 p
= 4 x 4 u
= 16 u
Number of more foolscaps that Jaslyn bought
= 16 u ÷ 4 u
= 4
Total number of foolscaps that Jaslyn bought
= 8 + 4
= 12
Answer(s): 12
