Question

The manager of a store orders mystery games that cost $7.30 and sells them for $15.33. What is the mark-up as a percentage?

Answer 1

In order to find the price increase in percentage terms, we divide the price difference by the cost price.

The difference:

• 
  `15.33-7.30=8.03`

Rate:

• 
  `(8.03)/(7.30)=(x)/(100)`

If we solve for
`x` in this equation, it will give us the price increase as a percentage.

• 
  `(7.30)x=(8.03)(100)`
• 
  `7.30x=803`
• 
  `x=(803)/(7.30)`
• 
  `x=110`

The price increase should be
`110`%.
