Wendy spent
35 of her money on 6 staplers and 3 markers. The cost of one marker was twice the cost of one stapler. She bought some more markers with
14 of her remaining money. How many markers did Wendy buy altogether?

3 p |
Cost of 1 stapler = 1 u
Cost of 1 marker = 2 u
Cost of 6 staplers = 6 x 1 u = 6 u
Cost of 3 markers = 3 x 2 u = 6 u
Total cost of 6 staplers and 3 markers
= 6 u + 6 u
= 12 u
6 p = 12 u
1 p = 12 ÷ 6 = 2 u
Amount that Wendy used to buy more markers
= 1 p
= 1 x 2 u
= 2 u
Number of more markers that Wendy bought
= 2 u ÷ 2 u
= 1
Total number of markers that Wendy bought
= 3 + 1
= 4
Answer(s): 4
