Emily's shop sold skirts and blouses. The skirts were sold at $60 each and each blouse was sold at ¹₂ of the price of each skirt. Emily sold ¹₃ of the items on the first day and collected $6930. ⁵₆ of the items sold on the first day were skirts.

1. How many blouses were sold on the first day?
2. What was the total number of items left after the first day?

(a)

Sold		Unsold	Total
1x6		2x6	3x6
Skirts	Blouses
5x1	1x1
5 u	1 u	12 u	18 u

The total number of skirts and blouses sold is repeated.  Make the total number of skirts and blouses sold the same.  LCM of 6 and 1 is 6.

	Skirts	Blouses	Total
Number	5 u	1 u	6 u
Value	$60	$30
Total value	300 u	30 u	330 u

Cost of each blouse
= ¹₂ x 60
= $30

Total amount collected from selling the skirts and the blouses on the first day
= 300 u + 30 u
= 330 u

330 u = 6930

1 u = 6930 ÷ 330 = 21

Number of blouses sold on the first day
= 1 u
= 21

(b)
Total number of items left after the first day
= 12 u
= 12 x 21
= 252

Answer(s): (a) 21; (b) 252
