Winnie spent $95 on some staplers, files and markers. The number of staplers she bought was ¹₂ the number of files. The number of markers she bought was ³₄ the number of files. The ratio of the amount of money she spent on the staplers, files and markers was 6 : 8 : 5. The files were sold at 2 for $10. Find the price of 1 stapler.

Amount spent
Staplers	Files	Markers	Total
6 u	8 u	5 u	$95

Total amount that Winnie spent on staplers, files and markers
= 6 u + 8 u + 5 u
= 19 u

19 u = 95

1 u = 95 ÷ 19 = 5

Amount that Winnie spent on files
= 8 u
= 8 x 5
= $40

Number of sets of files of 2 bought
= 40 ÷ 10
= 4

Number of files that Winnie bought
= 4 x 2
= 8

Number of items bought
Staplers	Files	Markers	Total
1x2	2x2
	4x1	3x1
2 p	4 p	3 p	9 p

The number of files bought is repeated.  Make the number of files bought is the same.  LCM of 2 and 4 is 4.

Number of files that Winnie bought = 4 p

4 p = 8

1 p = 8 ÷ 4 = 2

Number of staplers that Winnie bought
= 2 p
= 2 x 2
= 4

Amount that Winnie spent on staplers
= 6 u
= 6 x 5
= $30

Price of 1 stapler
= 30 ÷ 4
= $7.50

Answer(s): $7.50
