Barbara spent $171 on some markers, pencils and pens. The number of markers she bought was ²₃ the number of pencils. The number of pens she bought was ³₅ the number of pencils. The ratio of the amount of money she spent on the markers, pencils and pens was 8 : 5 : 6. The pencils were sold at 5 for $5. Find the price of 1 marker.

Amount spent
Markers	Pencils	Pens	Total
8 u	5 u	6 u	$171

Total amount that Barbara spent on markers, pencils and pens
= 8 u + 5 u + 6 u
= 19 u

19 u = 171

1 u = 171 ÷ 19 = 9

Amount that Barbara spent on pencils
= 5 u
= 5 x 9
= $45

Number of sets of pencils of 5 bought
= 45 ÷ 5
= 9

Number of pencils that Barbara bought
= 9 x 5
= 45

Number of items bought
Markers	Pencils	Pens	Total
2x5	3x5
	5x3	3x3
10 p	15 p	9 p	34 p

The number of pencils bought is repeated.  Make the number of pencils bought is the same.  LCM of 3 and 5 is 15.

Number of pencils that Barbara bought = 15 p

15 p = 45

1 p = 45 ÷ 15 = 3

Number of markers that Barbara bought
= 10 p
= 10 x 3
= 30

Amount that Barbara spent on markers
= 8 u
= 8 x 9
= $72

Price of 1 marker
= 72 ÷ 30
= $2.40

Answer(s): $2.40
