Question

10. Find the original price of an antique which was sold at £545 at a profit of 9%.

Answer 1

495.95

convert the percentage into a decimal

0.09

then do b=1-r

1 - 0.09 = 0.91

Now do 545 x 0.91

Answer: 495.95

Answer 2

The original price of the antique was £500.

Step-by-step explanation:

Let's assume that the original price of the antique was x.

We know that the antique was sold at a profit of 9%, which means that the selling price is 109% of the original price:

`Selling \: price = Original \: price + Profit`

`£545 = x + 0.09x \\ £545 = 1.09x`

To find the original price, we can divide both sides of the equation by 1.09:

`x = (545)/(1.09)`

`x = 500`

Therefore, the original price of the antique was £500.
