Zoe's shop sold vests and blouses. The vests were sold at $120 each and each blouse was sold at ³₄ of the price of each vest. Zoe sold ¹₅ of the items on the first day and collected $4410. ¹₂ of the items sold on the first day were vests.

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
1x2		4x2	5x2
Vests	Blouses
1x1	1x1
1 u	1 u	8 u	10 u

The total number of vests and blouses sold is repeated.  Make the total number of vests and blouses sold the same.  LCM of 2 and 1 is 2.

	Vests	Blouses	Total
Number	1 u	1 u	2 u
Value	$120	$90
Total value	120 u	90 u	210 u

Cost of each blouse
= ³₄ x 120
= $90

Total amount collected from selling the vests and the blouses on the first day
= 120 u + 90 u
= 210 u

210 u = 4410

1 u = 4410 ÷ 210 = 21

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

(b)
Total number of items left after the first day
= 8 u
= 8 x 21
= 168

Answer(s): (a) 21; (b) 168
