PSLE A company offered 80 toasters at 30% 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 80 toasters were sold in the first four days of the sale?
- During the sale, the discounted price of the toasters was $49. After the sale, the remaining toasters were sold without discount. What was the total amount of money collected from selling all 80 toasters?
(a)
The steepest line is from Day 2 to Day 3.
On Day 3, the most number of toasters was sold.
(b)
Number of toasters that were left at Day 4 = 32
Number of toasters that were sold for the first four days
= 80 - 32
= 48
Percentage of toasters that were sold for the first four days
=
4880 x 100%
= 60%
(c)
Number of toasters that were left at the end of the sale = 8
Number of toasters that were sold during the sale
= 80 - 8
= 72
Total amount that collected from the toasters sold
= 72 x 49
= $3528
Price of each toaster after 30% discount
= 100% - 30%
= 70%
70% of the price = 49
1% of the price = 49 ÷ 70 = 0.7
100% of the price = 100 x 0.7 = 70
Amount collected from selling the remaining toasters
= 8 x 70
= $560
Total amount collected from selling all the 80 toasters
= 3528 + 560
= $4088
Answer(s): (a) Day 3; (b) 60%; (c) $4088
