PSLE A company offered 200 hand blenders at 20% discount during a 7-day sale. The line graph shows the number of hand blenders left unsold at the end of each day.
- On which day was the most number of hand blenders sold? Give your answer in this format. (Eg Day 1)
- What percentage of the 200 hand blenders were sold in the first four days of the sale?
- During the sale, the discounted price of the hand blenders was $72. After the sale, the remaining hand blenders were sold without discount. What was the total amount of money collected from selling all 200 hand blenders?
(a)
The steepest line is from Day 2 to Day 3.
On Day 3, the most number of hand blenders was sold.
(b)
Number of hand blenders that were left at Day 4 = 100
Number of hand blenders that were sold for the first four days
= 200 - 100
= 100
Percentage of hand blenders that were sold for the first four days
=
100200 x 100%
= 50%
(c)
Number of hand blenders that were left at the end of the sale = 70
Number of hand blenders that were sold during the sale
= 200 - 70
= 130
Total amount that collected from the hand blenders sold
= 130 x 72
= $9360
Price of each hand blender after 20% discount
= 100% - 20%
= 80%
80% of the price = 72
1% of the price = 72 ÷ 80 = 0.9
100% of the price = 100 x 0.9 = 90
Amount collected from selling the remaining hand blenders
= 70 x 90
= $6300
Total amount collected from selling all the 200 hand blenders
= 9360 + 6300
= $15660
Answer(s): (a) Day 3; (b) 50%; (c) $15660
