- 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 six days of the sale?
- During the sale, the discounted price of the toasters was $72. After the sale, the remaining toasters were sold without discount. What was the total amount of money collected from selling all 100 toasters?
(a)
Steepest line is from Day 3 to Day 4.
On Da
y 4, the most number of toasters was sold. (b) Number of toasters that were left at Day 6 = 45 Number of toasters that were sold for the first six days = 100 - 45 = 55 Percentage of toasters that were sold for the first six days = 55100 x 100% = 55%
(c)
Number of toasters that were left at the end of the sale = 35
Number of toasters that were sold during the sale
= 100 - 35
= 65
Total amount that collected from the toasters sold
= 65 x 72
= $4680
Price of each toaster after 10% discount
= 100% - 10%
= 90%
90% of the price = 72
1% of the price = 72 ÷ 90 = 0.8
100% of the price = 100 x 0.8 = 80
Amount collected from selling the remaining toasters
= 35 x 80
= $2800
Total amount collected from selling all the 100 toasters
= 4680 + 2800
= $7480
Answer(s): (a) Day 4; (b) 55%; (c) $7480
