Find the new price for the markup given. Round to the nearest cent if necessary. $3.00 marked up 72%
Marrrta [24]

Answer:

$5.16

Explanation:

Okay, so the first step is to move the decimal point of the 72% over to the left twice. Since it is a whole number, the decimal is at the back. So, the number went from 72 to .72.

After that, multiply 3.00 by .72 Like this:

3.00 * .72 = 2.16

The last step is to add the original number to that number. Like this:

3.00 + 2.16 = 5.16

Hope this helps !

Normally a game console costs $525, but you only have $450. How much would the game console need to be discounted (as a percent)
klemol [59]

Answer: 14.29 or rounded up to 15%

Step-by-step explanation:

525 - 450 = 75

You need at least $75 off the price to have enough money.

75/525 = x/100

Solve for X

75 * 100 = 7500

7500/525 = 14.2857143

If answer should be a whole percentage you would need the discount to be 15% in order to not fall short on funds.
