- What percentage of the 200 juicers were sold in the first six days of the sale?
- During the sale, the discounted price of the juicers was $72. After the sale, the remaining juicers were sold without discount. What was the total amount of money collected from selling all 200 juicers?
(a)
Steepest line is from Day 3 to Day 4.
On Da
y 4, the most number of juicers was sold. (b) Number of juicers that were left at Day 6 = 50 Number of juicers that were sold for the first six days = 200 - 50 = 150 Percentage of juicers that were sold for the first six days = 150200 x 100% = 75%
(c)
Number of juicers that were left at the end of the sale = 20
Number of juicers that were sold during the sale
= 200 - 20
= 180
Total amount that collected from the juicers sold
= 180 x 72
= $12960
Price of each juicer after 20% discount
= 100% - 20%
= 80%
80% of the price = 72
1% of the price = 72 ÷ 80 = 0.9
100% of the price = 100 x 0.9 = 90
Amount collected from selling the remaining juicers
= 20 x 90
= $1800
Total amount collected from selling all the 200 juicers
= 12960 + 1800
= $14760
Answer(s): (a) Day 4; (b) 75%; (c) $14760
