Cost of 1 marker = 1 u
Cost of 1 file = 4 u
Cost of 10 markers = 10 x 1 u = 10 u
Cost of 8 files = 8 x 4 u = 32 u
Cost of 10 markers + 8 files
= 10 u + 32 u
= 42 u
3 p = 42 u
1 p = 42 u ÷ 3 = 14 u
Amount of remaining money that Raeann spent on buying more markers
=
67 x 14 u
= 12 u
Number of markers that Raeann bought with
67 of her remaining money
= 12 u ÷ 1 u
= 12
Total number of markers that Raeann bought
= 10 + 12
= 22
Answer(s): 22
