PSLE A company offered 200 toasters at 20% 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 200 toasters were sold in the first five days of the sale?
- During the sale, the discounted price of the toasters was $136. After the sale, the remaining toasters were sold without discount. What was the total amount of money collected from selling all 200 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 = 100 Number of toasters that were sold for the first five days = 200 - 100 = 100 Percentage of toasters that were sold for the first five days
=
100200 x 100%
= 50%
(c)
Number of toasters that were left at the end of the sale = 60
Number of toasters that were sold during the sale
= 200 - 60
= 140
Total amount that collected from the toasters sold
= 140 x 136
= $19040
Price of each toaster after 20% discount
= 100% - 20%
= 80%
80% of the price = 136
1% of the price = 136 ÷ 80 = 1.7
100% of the price = 100 x 1.7 = 170
Amount collected from selling the remaining toasters
= 60 x 170
= $10200
Total amount collected from selling all the 200 toasters
= 19040 + 10200
= $29240
Answer(s): (a) Day
2; (b) 50%; (c) $29240
