So here, we are starting with two numbers: the original price, and the price after the percent increase.
First, we need to find the differences between the prices to figure out how much of a difference the percent made. $181.09 - $102.30 = $78.79
$78.79 is how much money the original price was increased by. We can find the percent change using this, since this number is what percent of the original price went up.
So now: $78.78 / $102.30 = .77018
And now, we convert that to percent: 77%
The markup was 77%.
70/1000 = 35/500=7/100
First you divide 70 by 2 and 1000 by 2 = 35/500.
Then you divide 35/5 and 500/5 and the answer is 7/100.
- Hope this helps
Radius is 5 cm. is the answer
