- What percentage of the 200 juicers were sold in the first five days of the sale?
- During the sale, the discounted price of the juicers was $30. After the sale, the remaining juicers were sold without discount. What was the total amount of money collected from selling all 200 juicers?
(a)
The steepest line is from Day 1 to Day 2.
On Day
2, the most number of juicers was sold.
(b)
Number of juicers that were left at Day
5 = 80 Number of juicers that were sold for the first five days = 200 - 80 = 120 Percentage of juicers that were sold for the first five days
=
120200 x 100%
= 60%
(c)
Number of juicers that were left at the end of the sale = 30
Number of juicers that were sold during the sale
= 200 - 30
= 170
Total amount that collected from the juicers sold
= 170 x 30
= $5100
Price of each juicer after 40% discount
= 100% - 40%
= 60%
60% of the price = 30
1% of the price = 30 ÷ 60 = 0.5
100% of the price = 100 x 0.5 = 50
Amount collected from selling the remaining juicers
= 30 x 50
= $1500
Total amount collected from selling all the 200 juicers
= 5100 + 1500
= $6600
Answer(s): (a) Day
2; (b) 60%; (c) $6600
