Question

An $42 item was marked down by 50% what is the new cost of the item?

Answer 1

Answer:

New Cost of item is $\ 21$

Step-by-step explanation:

Given:

Original Cost of item = $\ 42$

Item was marked down by $50\%$

To Calculate Cost after $50\%$ marked  down we need to multiply original cost by 50 and then divide by hundred.

Cost after  marked down = $\frac{42 \times 50}{100}= \ 21$

Now New cost of the item is calculated by Subtracting Cost after $50\%$ marked down by Original Cost of item.

New cost of the item =  $\ 42 - \ 21 = \ 21$
