- What percentage of the 100 juicers were sold in the first five days of the sale?
- During the sale, the discounted price of the juicers was $117. After the sale, the remaining juicers were sold without discount. What was the total amount of money collected from selling all 100 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 = 25 Number of juicers that were sold for the first five days = 100 - 25 = 75 Percentage of juicers that were sold for the first five days
=
75100 x 100%
= 75%
(c)
Number of juicers that were left at the end of the sale = 5
Number of juicers that were sold during the sale
= 100 - 5
= 95
Total amount that collected from the juicers sold
= 95 x 117
= $11115
Price of each juicer after 10% discount
= 100% - 10%
= 90%
90% of the price = 117
1% of the price = 117 ÷ 90 = 1.3
100% of the price = 100 x 1.3 = 130
Amount collected from selling the remaining juicers
= 5 x 130
= $650
Total amount collected from selling all the 100 juicers
= 11115 + 650
= $11765
Answer(s): (a) Day
2; (b) 75%; (c) $11765
