- What percentage of the 150 deep fryers were sold in the first five days of the sale?
- During the sale, the discounted price of the deep fryers was $28. After the sale, the remaining deep fryers were sold without discount. What was the total amount of money collected from selling all 150 deep fryers?
(a)
The steepest line is from Day 1 to Day 2.
On Day
2, the most number of deep fryers was sold.
(b)
Number of deep fryers that were left at Day
5 = 60 Number of deep fryers that were sold for the first five days = 150 - 60 = 90 Percentage of deep fryers that were sold for the first five days
=
90150 x 100%
= 60%
(c)
Number of deep fryers that were left at the end of the sale = 20
Number of deep fryers that were sold during the sale
= 150 - 20
= 130
Total amount that collected from the deep fryers sold
= 130 x 28
= $3640
Price of each deep fryer after 30% discount
= 100% - 30%
= 70%
70% of the price = 28
1% of the price = 28 ÷ 70 = 0.4
100% of the price = 100 x 0.4 = 40
Amount collected from selling the remaining deep fryers
= 20 x 40
= $800
Total amount collected from selling all the 150 deep fryers
= 3640 + 800
= $4440
Answer(s): (a) Day
2; (b) 60%; (c) $4440
