Raeann spent
27 of her money on 4 foolscaps and 6 staplers. The cost of one stapler was twice the cost of one foolscap. She bought some more staplers with
14 of her remaining money. How many staplers did Raeann buy altogether?

Cost of 1 foolscap = 1 u
Cost of 1 stapler = 2 u
Cost of 4 foolscaps = 4 x 1 u = 4 u
Cost of 6 staplers = 6 x 2 u = 12 u
Total cost of 4 foolscaps and 6 staplers
= 4 u + 12 u
= 16 u
8 p = 16 u
1 p = 16 ÷ 8 = 2 u
Amount that Raeann used to buy more staplers
= 5 p
= 5 x 2 u
= 10 u
Number of more staplers that Raeann bought
= 10 u ÷ 2 u
= 5
Total number of staplers that Raeann bought
= 6 + 5
= 11
Answer(s): 11
