Answer:

4.21×10^10

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Hope this helps :)

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%
