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

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