- What percentage of the 200 blenders were sold in the first six days of the sale?
- During the sale, the discounted price of the blenders was $84. After the sale, the remaining blenders were sold without discount. What was the total amount of money collected from selling all 200 blenders?
(a)
Steepest line is from Day 3 to Day 4.
On Da
y 4, the most number of blenders was sold. (b) Number of blenders that were left at Day 6 = 60 Number of blenders that were sold for the first six days = 200 - 60 = 140 Percentage of blenders that were sold for the first six days = 140200 x 100% = 70%
(c)
Number of blenders that were left at the end of the sale = 50
Number of blenders that were sold during the sale
= 200 - 50
= 150
Total amount that collected from the blenders sold
= 150 x 84
= $12600
Price of each blender after 40% discount
= 100% - 40%
= 60%
60% of the price = 84
1% of the price = 84 ÷ 60 = 1.4
100% of the price = 100 x 1.4 = 140
Amount collected from selling the remaining blenders
= 50 x 140
= $7000
Total amount collected from selling all the 200 blenders
= 12600 + 7000
= $19600
Answer(s): (a) Day 4; (b) 70%; (c) $19600
