The original price is $200

Question :

The price of a dress is reduced by 50%. When the dress still does not sell, it is reduced by 50% of the reduced price. If the price of the dress after both reductions is $50, what was the original price?

Step-by-step explanation:

Let x represent the original price of the dress.

First reduction

After first reduction the value of the price is given as;

p1 = x - 50% of x = (1-0.50)x = 0.5x

p1 = 0.5x

Second reduction

After the second reduction the value of the price is given as;

p2 = p1 - 50% of p1 = (1-0.50)p1 = (0.50)0.50x

p2 = 0.25x .....1

Since, p2 is given

p2 = $50

Substituting into equation 1

$50 = 0.25x

x = $50/0.25 = $200

x = $200

The original price is $200

Answer:

Average day end balance using weighted average = $1,316.667

Average day end balance using simple average = $1,050

Step-by-step explanation:

Provided opening balance = $1,200

During the month addition in such balance = $500

New balance as on 16 November = $1,200 + $500 = $1,700

Further by the end of month of November balance after payment = $1,700 - $800

= $900

Thus, opening balance = $1,200

Closing = $900

Simple average = $\frac{1,200 + 9,00}{2} = 1,050$

Day end balance = $1,050

For this weighted average can be done

First 15 days balance = $1,200 as no transaction was done.

From 16 to 25 November balance increased by $500 = $1,700 for 10 days

Remaining days = 5 days = $1,700 - $800 paid = $900

Using weighted average we have

$\frac{(1,200 \times 15) + (1,700 \times 10) + (900 \times 5)}{30} = \frac{39,500}{30} = 1,316.667$

Day end balance = $1,316.667

Please help! I'm not really good with percent questions

Andre45 [30]

You first have to find out the total number of questions there was on the unit test. To do that you write 90 over 100 equals 45 over x. X represents the total number of questions. Then cross multiply. you should get 90x=4500.then divide 4500 by 90 and the answer should be x=50. then take 50 subtract 2 and you should get 48. then take 48 and divide it by 50. the answer you should get is .96. then take .96 multiply it by 100 and you should get 96. so Emmanuel's percent on the unit test is 96%.
