PSLE A company offered $(dn0) food processors at 40% discount during a 7-day sale. The line graph shows the number of food processors left unsold at the end of each day.
- On which day was the most number of food processors sold? Give your answer in this format. (Eg Day 1)
- What percentage of the 200 food processors were sold in the first six days of the sale?
- During the sale, the discounted price of the food processors was $108. After the sale, the remaining food processors were sold without discount. What was the total amount of money collected from selling all 200 food processors?
(a)
Steepest line is from Day 3 to Day 4.
On Da
y 4, the most number of food processors was sold. (b) Number of food processors that were left at Day 6 = 60 Number of food processors that were sold for the first six days = 200 - 60 = 140 Percentage of food processors that were sold for the first six days = 140200 x 100% = 70%
(c)
Number of food processors that were left at the end of the sale = 50
Number of food processors that were sold during the sale
= 200 - 50
= 150
Total amount that collected from the food processors sold
= 150 x 108
= $16200
Price of each food processor after 40% discount
= 100% - 40%
= 60%
60% of the price = 108
1% of the price = 108 ÷ 60 = 1.8
100% of the price = 100 x 1.8 = 180
Amount collected from selling the remaining food processors
= 50 x 180
= $9000
Total amount collected from selling all the 200 food processors
= 16200 + 9000
= $25200
Answer(s): (a) Day 4; (b) 70%; (c) $25200
