Cost of 1 marker = 1 u
Cost of 1 stapler = 2 u
Cost of 10 markers = 10 x 1 u = 10 u
Cost of 7 staplers = 7 x 2 u = 14 u
Cost of 10 markers + 7 staplers
= 10 u + 14 u
= 24 u
3 p = 24 u
1 p = 24 u ÷ 3 = 8 u
Amount of remaining money that Xylia spent on buying more markers
=
34 x 8 u
= 6 u
Number of markers that Xylia bought with
34 of her remaining money
= 6 u ÷ 1 u
= 6
Total number of markers that Xylia bought
= 10 + 6
= 16
Answer(s): 16
