A. 0.5m


B. 1.5m


C. 3m


D. 3.5m

Answer 1

`Selling\ Price = 1.5m`

Explanation:

Given

`Market\ Price = m`

`Discount = 50\%`

Selling Price = 3 * Amount she paid

Required

Determine the selling price

If she gets a discount of 50%, then she pays 50% (i.e. 100 - 50%).

So, the amount she paid is:

`Amount = 50\% * Market\ Price`

`Amount = 50\% * m`

`Amount = 0.5* m`

`Amount = 0.5m`

She sells at three times that amount.

So, the selling price is:

`Selling\ Price = 3 * 0.5m`

`Selling\ Price = 1.5m`
