Answer:
New Cost of item is [tex]\$ 21[/tex]
Step-by-step explanation:
Given:
Original Cost of item = [tex]\$ 42[/tex]
Item was marked down by [tex]50\%[/tex]
To Calculate Cost after [tex]50\%[/tex] marked down we need to multiply original cost by 50 and then divide by hundred.
Cost after marked down = [tex]\frac{42 \times 50}{100}= \$21[/tex]
Now New cost of the item is calculated by Subtracting Cost after [tex]50\%[/tex] marked down by Original Cost of item.
New cost of the item = [tex]\$ 42 - \$ 21 = \$21[/tex]
