PSLE A company offered 100 toasters at 40% discount during a 7-day sale. The line graph shows the number of toasters left unsold at the end of each day.
- On which day was the most number of toasters sold? Give your answer in this format. (Eg Day 1)
- What percentage of the 100 toasters were sold in the first five days of the sale?
- During the sale, the discounted price of the toasters was $24. After the sale, the remaining toasters were sold without discount. What was the total amount of money collected from selling all 100 toasters?
(a)
The steepest line is from Day 1 to Day 2.
On Day
2, the most number of toasters was sold.
(b)
Number of toasters that were left at Day
5 = 40 Number of toasters that were sold for the first five days = 100 - 40 = 60 Percentage of toasters that were sold for the first five days
=
60100 x 100%
= 60%
(c)
Number of toasters that were left at the end of the sale = 25
Number of toasters that were sold during the sale
= 100 - 25
= 75
Total amount that collected from the toasters sold
= 75 x 24
= $1800
Price of each toaster after 40% discount
= 100% - 40%
= 60%
60% of the price = 24
1% of the price = 24 ÷ 60 = 0.4
100% of the price = 100 x 0.4 = 40
Amount collected from selling the remaining toasters
= 25 x 40
= $1000
Total amount collected from selling all the 100 toasters
= 1800 + 1000
= $2800
Answer(s): (a) Day
2; (b) 60%; (c) $2800
