Linda spent ³₄ of her money on 13 staplers and 8 notebooks. The cost of each notebook is 4 times the cost of each stapler. She bought some more staplers with ²₃ of her remaining money. How many staplers did Linda buy altogether?

13 staplers + 8 notebooks		Remaining  amount		Total amount
3 p = 45 u		1 p = 15 u		4 p
13 staplers	8 notebooks	More staplers	Left
		2	1
13 u	32 u	10 u

Cost of 1 stapler = 1 u
Cost of 1 notebook = 4 u

Cost of 13 staplers = 13 x 1 u = 13 u
Cost of 8 notebooks = 8 x 4 u = 32 u

Cost of 13 staplers + 8 notebooks
= 13 u + 32 u
= 45 u

3 p = 45 u

1 p = 45 u ÷ 3 = 15 u

Amount of remaining money that Linda spent on buying more staplers
= ²₃ x 15 u
= 10 u

Number of staplers that Linda bought with ²₃ of her remaining money
= 10 u ÷ 1 u
= 10

Total number of staplers that Linda bought
= 13 + 10
= 23

Answer(s): 23
