- What percentage of the 200 blenders were sold in the first six days of the sale?
- During the sale, the discounted price of the blenders was $8. After the sale, the remaining blenders were sold without discount. What was the total amount of money collected from selling all 200 blenders?
(a)
Steepest line is from Day 3 to Day 4.
On Da
y 4, the most number of blenders was sold. (b) Number of blenders that were left at Day 6 = 50 Number of blenders that were sold for the first six days = 200 - 50 = 150 Percentage of blenders that were sold for the first six days = 150200 x 100% = 75%
(c)
Number of blenders that were left at the end of the sale = 30
Number of blenders that were sold during the sale
= 200 - 30
= 170
Total amount that collected from the blenders sold
= 170 x 8
= $1360
Price of each blender after 20% discount
= 100% - 20%
= 80%
80% of the price = 8
1% of the price = 8 ÷ 80 = 0.1
100% of the price = 100 x 0.1 = 10
Amount collected from selling the remaining blenders
= 30 x 10
= $300
Total amount collected from selling all the 200 blenders
= 1360 + 300
= $1660
Answer(s): (a) Day 4; (b) 75%; (c) $1660
