Usha spent
27 of her money on 2 markers and 7 staplers. The cost of one stapler was twice the cost of one marker. She bought some more staplers with
14 of her remaining money. How many staplers did Usha buy altogether?

1x5 |

5 p |
15 p |
Cost of 1 marker = 1 u
Cost of 1 stapler = 2 u
Cost of 2 markers = 2 x 1 u = 2 u
Cost of 7 staplers = 7 x 2 u = 14 u
Total cost of 2 markers and 7 staplers
= 2 u + 14 u
= 16 u
8 p = 16 u
1 p = 16 ÷ 8 = 2 u
Amount that Usha used to buy more staplers
= 5 p
= 5 x 2 u
= 10 u
Number of more staplers that Usha bought
= 10 u ÷ 2 u
= 5
Total number of staplers that Usha bought
= 7 + 5
= 12
Answer(s): 12
