PSLE A company offered $(dn0) 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 80 blenders were sold in the first six days of the sale?
- During the sale, the discounted price of the blenders was $6. After the sale, the remaining blenders were sold without discount. What was the total amount of money collected from selling all 80 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 = 32 Number of blenders that were sold for the first six days = 80 - 32 = 48 Percentage of blenders that were sold for the first six days = 4880 x 100% = 60%
(c)
Number of blenders that were left at the end of the sale = 24
Number of blenders that were sold during the sale
= 80 - 24
= 56
Total amount that collected from the blenders sold
= 56 x 6
= $336
Price of each blender after 40% discount
= 100% - 40%
= 60%
60% of the price = 6
1% of the price = 6 ÷ 60 = 0.1
100% of the price = 100 x 0.1 = 10
Amount collected from selling the remaining blenders
= 24 x 10
= $240
Total amount collected from selling all the 80 blenders
= 336 + 240
= $576
Answer(s): (a) Day 4; (b) 60%; (c) $576
