Discount Desk Furniture A Math Question About A Sale?
9 comments:
The selling price is $ 320.
50% discount on retail sales:
320 * 0.50 = 160.
The store had an "additional revenue" 20% discount. This means that the table will cost 80% of the purchase price.
160 * 0.80 = 128
$ 128
The selling price is $ 320.

The wording of the question did not specify what the other is off 20%. If the office of the first prize, then the discount is 70%,
1-0,7 = 30% = 0.3 on the left side
The answer is 320 times 0.3 = $ 96
Since this is not a response from 20% to the price after discount compared to 50%, so that after the reduction of 50%
320 times 0.5 = 160
Multiply 20% of what it means by 0.8 (1-0,2)
160 x 0.8 = $ 128
Answer is C.
First, they took 50% of retail prices. So $ is 320 less 50% of 320
320-0.5 (320) = $ 160
Then they took an additional 20%. So $ is 160 less 20% $ 160
160-0.2 (160) = $ 128
$ 320 50% $ 160
Another 20% extra is 20/100 * 320 = 64 off off
160-64 = 96 dollars is not the answer.
If the additional 20% discount on the selling price?
In this case,
20/100, 20% of 160 = 32
160 -31 = 128 Answer C
First find 50%
50% $ 320 = $ 320 / 2 = $ 160
Then you will find the 20%
20% 10% x 2
10% to $ 160 = $ 16
x 2 = $ 32
As it is reduced by 20% NO 20% deduction of $ 32 $ 160
What $ 128
$ 320 * 50% = $ 160
$ 160 * (1-20% = 80%) = $ 128
The answer is: C $ 128
128
320 / 2 = 160
160 *. 2 = 32
160-32 = 128
$ 320 *. 5 *. 8 = $ 128
