Question

In a '70% off sale, a dress was £48.
Work out the original price.

Answer 1

The original price of the dress was £160 before the 70% discount. This is calculated by dividing the discounted price (£48) by the remaining percentage after the discount (30%).

Step-by-step explanation:

To work out the original price of a dress that is now £48 after a 70% off sale, we need to determine what the £48 represents in terms of the original price. The £48 is 30% of the original price because 100% - 70% = 30%. To find the original price, divide the sale price by the percentage that represents the remaining amount after the discount.

Let's set up the equation where the original price is represented by x. Since £48 is 30% of x, we write it as 0.30x = £48. To find x, we divide both sides by 0.30:

£48 ÷ 0.30 = x

x = £160

Therefore, the original price of the dress was £160 before the 70% discount.

Answer 2

£160

Step-by-step explanation:

In a 70% off sale, a dress was £48.

Work out the original price.

100% - 70% = 30%

If the dress was £48 when it was 70% off, then that means that £48. is only 30% of the original price.

STEP 1: Write 30% as a decimal.

30% = 0.3

STEP 2: Divide 48 by 0.3.

48/0.3 = 160

So, that means that the original price of the dress must have been £160.

£160 is our answer.
