PSLE A company offered 180 hand blenders at 10% 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 180 hand blenders were sold in the first four days of the sale?
- During the sale, the discounted price of the hand blenders was $162. After the sale, the remaining hand blenders were sold without discount. What was the total amount of money collected from selling all 180 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 = 90
Number of hand blenders that were sold for the first four days
= 180 - 90
= 90
Percentage of hand blenders that were sold for the first four days
=
90180 x 100%
= 50%
(c)
Number of hand blenders that were left at the end of the sale = 40
Number of hand blenders that were sold during the sale
= 180 - 40
= 140
Total amount that collected from the hand blenders sold
= 140 x 162
= $22680
Price of each hand blender after 10% discount
= 100% - 10%
= 90%
90% of the price = 162
1% of the price = 162 ÷ 90 = 1.8
100% of the price = 100 x 1.8 = 180
Amount collected from selling the remaining hand blenders
= 40 x 180
= $7200
Total amount collected from selling all the 180 hand blenders
= 22680 + 7200
= $29880
Answer(s): (a) Day 3; (b) 50%; (c) $29880
