- 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 $117. 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 = 20 Number of toasters that were sold for the first six days = 100 - 20 = 80 Percentage of toasters that were sold for the first six days = 80100 x 100% = 80%
(c)
Number of toasters that were left at the end of the sale = 5
Number of toasters that were sold during the sale
= 100 - 5
= 95
Total amount that collected from the toasters sold
= 95 x 117
= $11115
Price of each toaster after 10% discount
= 100% - 10%
= 90%
90% of the price = 117
1% of the price = 117 ÷ 90 = 1.3
100% of the price = 100 x 1.3 = 130
Amount collected from selling the remaining toasters
= 5 x 130
= $650
Total amount collected from selling all the 100 toasters
= 11115 + 650
= $11765
Answer(s): (a) Day 4; (b) 80%; (c) $11765
