Question

a man spends $210 on a shirt. If the shirt has been marked down 30% when he bought it, what was the original price?

Answer 1

Let's say the original price of the shirt was x.
If the shirt has been marked down 30%, then the price after the markdown is x - 0.30x = 0.70x.

We know that the man spent $210 on the shirt, so 0.70x = $210.
Dividing both sides of the equation by 0.70, we get x = $210 / 0.70 = $300.

Therefore, the original price of the shirt was $300.
