A because it will always be 99
15% = .15
add 1.00 to include the original amount
9 *(1+0.15) = 10.35
so $10.35

<h3>What is the relative frequency?</h3>
The relative frequency describes through a percentage (0% to 100%) or an equivalent, the frequency of an event. Here are some examples:
- If in a city it rains 15 out of the 30 days, the relative frequency is 50% or 0.5.
- If a specific soccer team never wins matches, the relative frequency for winning is 0% or 0.
<h3>How to calculate relative frequency?</h3>
To find relative frequency simply use this formula
- total of occurrence of a specific event/ total possible events or outcomes.
Let's use this formula to calculate the frequency of classes failed by each child.
1/ 3 = 0.33
1/3 = 0.3
2/3 = 0.66
0/ 3 = 0
1/3 =0.33
1/3 = 0.33
2/3 = 0.66
0 /3 = 0
Finally, create the bar graph using the information.
