Gillian spent
35 of her money on 4 glues and 8 staplers. The cost of one stapler was four times the cost of one glue. She bought some more staplers with
13 of her remaining money. How many staplers did Gillian buy altogether?

| 9 p |
2 p |
4 p |
Cost of 1 glue = 1 u
Cost of 1 stapler = 4 u
Cost of 4 glues = 4 x 1 u = 4 u
Cost of 8 staplers = 8 x 4 u = 32 u
Total cost of 4 glues and 8 staplers
= 4 u + 32 u
= 36 u
9 p = 36 u
1 p = 36 ÷ 9 = 4 u
Amount that Gillian used to buy more staplers
= 2 p
= 2 x 4 u
= 8 u
Number of more staplers that Gillian bought
= 8 u ÷ 4 u
= 2
Total number of staplers that Gillian bought
= 8 + 2
= 10
Answer(s): 10
