PSLE A company offered 100 blenders at 40% 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 100 blenders were sold in the first five days of the sale?
- During the sale, the discounted price of the blenders was $78. After the sale, the remaining blenders were sold without discount. What was the total amount of money collected from selling all 100 blenders?
(a)
The steepest line is from Day 1 to Day 2.
On Day
2, the most number of blenders was sold.
(b)
Number of blenders that were left at Day
5 = 35 Number of blenders that were sold for the first five days = 100 - 35 = 65 Percentage of blenders that were sold for the first five 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 78
= $6240
Price of each blender after 40% discount
= 100% - 40%
= 60%
60% of the price = 78
1% of the price = 78 ÷ 60 = 1.3
100% of the price = 100 x 1.3 = 130
Amount collected from selling the remaining blenders
= 20 x 130
= $2600
Total amount collected from selling all the 100 blenders
= 6240 + 2600
= $8840
Answer(s): (a) Day
2; (b) 65%; (c) $8840
