The percent of the original price after markup is 98%

<h3>Mark up and discounts</h3>

Given the following parameters

  • Original price of tablet = $460

If during a sale, a store offered a 15% discount on a tablet, the new price after discount will be:

New price = 0.85 * 460

  • New price = $391

If the tablet computer was marked up by 15% after the discount, then the price after the markup is given as:

  • Price after markup = 1.15 * 391
    Price after markup = $450

To get the required percent;

x% of 460 = 450
x% = 450/460

x% = 0.978

x = 98%

Hence the percent of the original price after markup is 98%
