Answer 1

Given:

Find the actual cost of an item that is at present $100 that is 8% off.

To find:

8% of x = $100

Solution:

• Let the actual cost be x.
• 
  `8\% \: of \: x = 100`
• 
  `(8\%)/(100) * x = 100`
• 
  `x = 100 * (100)/(8)`
• 
  `x = (10000)/(8)`
• 
  `x = 1250`
• Therefore, the cost of the item was $125 or $1250.
