- On which day was the most number of blenders sold? Give your answer in this format. (Eg Day 1)
- What percentage of the 100 blenders were sold in the first six days of the sale?
- During the sale, the discounted price of the blenders was $128. After the sale, the remaining blenders were sold without discount. What was the total amount of money collected from selling all 100 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 = 35 Number of blenders that were sold for the first six days = 100 - 35 = 65 Percentage of blenders that were sold for the first six days = 65100 x 100% = 65%
(c)
Number of blenders that were left at the end of the sale = 20
Number of blenders that were sold during the sale
= 100 - 20
= 80
Total amount that collected from the blenders sold
= 80 x 128
= $10240
Price of each blender after 20% discount
= 100% - 20%
= 80%
80% of the price = 128
1% of the price = 128 ÷ 80 = 1.6
100% of the price = 100 x 1.6 = 160
Amount collected from selling the remaining blenders
= 20 x 160
= $3200
Total amount collected from selling all the 100 blenders
= 10240 + 3200
= $13440
Answer(s): (a) Day 4; (b) 65%; (c) $13440
