Cost of 1 file = 1 u
Cost of 1 stapler = 3 u
Cost of 14 files = 14 x 1 u = 14 u
Cost of 6 staplers = 6 x 3 u = 18 u
Cost of 14 files + 6 staplers
= 14 u + 18 u
= 32 u
2 p = 32 u
1 p = 32 u ÷ 2 = 16 u
Amount of remaining money that Joelle spent on buying more files
=
34 x 16 u
= 12 u
Number of files that Joelle bought with
34 of her remaining money
= 12 u ÷ 1 u
= 12
Total number of files that Joelle bought
= 14 + 12
= 26
Answer(s): 26
