- What percentage of the 100 juicers were sold in the first six days of the sale?
- During the sale, the discounted price of the juicers was $133. After the sale, the remaining juicers were sold without discount. What was the total amount of money collected from selling all 100 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 = 100 - 50 = 50 Percentage of juicers that were sold for the first six days = 50100 x 100% = 50%
(c)
Number of juicers that were left at the end of the sale = 45
Number of juicers that were sold during the sale
= 100 - 45
= 55
Total amount that collected from the juicers sold
= 55 x 133
= $7315
Price of each juicer after 30% discount
= 100% - 30%
= 70%
70% of the price = 133
1% of the price = 133 ÷ 70 = 1.9
100% of the price = 100 x 1.9 = 190
Amount collected from selling the remaining juicers
= 45 x 190
= $8550
Total amount collected from selling all the 100 juicers
= 7315 + 8550
= $15865
Answer(s): (a) Day 4; (b) 50%; (c) $15865
