PSLE A company offered 80 blenders at 20% discount during a 7-day sale. The line graph shows the number of blenders left unsold at the end of each day.
- On which day was the most number of blenders sold? Give your answer in this format. (Eg Day 1)
- What percentage of the 80 blenders were sold in the first four days of the sale?
- During the sale, the discounted price of the blenders was $104. After the sale, the remaining blenders were sold without discount. What was the total amount of money collected from selling all 80 blenders?
(a)
The steepest line is from Day 2 to Day 3.
On Day 3, the most number of blenders was sold.
(b)
Number of blenders that were left at Day 4 = 36
Number of blenders that were sold for the first four days
= 80 - 36
= 44
Percentage of blenders that were sold for the first four days
=
4480 x 100%
= 55%
(c)
Number of blenders that were left at the end of the sale = 12
Number of blenders that were sold during the sale
= 80 - 12
= 68
Total amount that collected from the blenders sold
= 68 x 104
= $7072
Price of each blender after 20% discount
= 100% - 20%
= 80%
80% of the price = 104
1% of the price = 104 ÷ 80 = 1.3
100% of the price = 100 x 1.3 = 130
Amount collected from selling the remaining blenders
= 12 x 130
= $1560
Total amount collected from selling all the 80 blenders
= 7072 + 1560
= $8632
Answer(s): (a) Day 3; (b) 55%; (c) $8632
