Question

What was the original price of the table

Table was on sale for 268.80 the price is 72% less than original price

Answer 1

O = Original

O(1 - .72) = 268.80

O(.28) = 268.80

O = 268.80/.28 = $960

Answer 2

Lets call the unknown original price P

We know that $268.8 is 28% of the original price, since a 72% discount was applied (100%-72%=28%)

Therefore, we can write: P * 0.28 = $268.8, since the price paid is 28% of the original price

By rewritting the equation, we get: P = $268.8 / 0.28

Solving $268.8/0.28 gives $960, which is the answer

Answer 3

Let's set the original price of the table (which we're solving for) as the variable x.

We know that the price of the table after taking away 72% of the original price is $268.80, which allows us to write out an important equation:

$268.80 = x * (100% - 72%)

$268.80 = x * (1 - 0.72)

$268.80 = x * 0.28

This equation is taking x and multiplying it by (100% - 72%), which written in decimal form is (1 - 0.72). That value can be written as either 28% or 0.28, and what it means is that after removing 72% of the original price, only 28% of the original price is left, which the question has told us is worth $268.80. Note that we'll be using 0.28 instead of 28% since we can only use decimals to multiply into money values. Continuing from our equation above:

$268.80 = x * 0.28

$268.80 / 0.28 = x

x = $960

By dividing on both sides by 0.28, we can get x by itself on one side to be able to solve for it.

Answer: $960

Answer 4

Since you know that the original price was 72% more, you can assume that the price you have right now is 28% of the original price because 100-72 = 28.

Then, you can set up a cross multiplication problem:

268.80 28

--------- = -------

x 100

For you can assume that what you have is 28% of the original price so you want to find the original full price which would be 100% of the price.

Cross multiply

268.80 = (.28)x

Then divide to find X (full price)

X = 960

Answer 5

To determine the original price of the table, we need to calculate the price before the 72% discount was applied.

Let's assume the original price of the table is "x".

According to the information provided, the table was on sale for 72% less than the original price. This means the sale price is equal to 100% - 72% = 28% of the original price.

We can set up the following equation to represent this relationship:

0.28x = 268.80

To solve for "x," we divide both sides of the equation by 0.28:

x = 268.80 / 0.28

Calculating this, we find:

x ≈ 960

Therefore, the original price of the table was approximately $960.
