Answer:
19,324
Step-by-step explanation:
The original amount is 100% of the original amount since 100% means a whole amount.
A 21% increase means that the new amount will be 100% + 21% = 121% of the original amount.
Now we calculate 121% of 15,970.
To find a percent of a number, multiply the percent by the number. First, divide the percent by 100 to change it into a decimal.
121% of 15,970 =

Attached is what you can do on excel.
Add the values as presented on the image. Select the values and then go t the menu "Insert" and look for "Charts" and then "Insert scatter chart". After this, select one of the dots from the graph and then press the right button of the mouse and select "add trendline". Now you have a trend line. Format the trendline selecting the option "Display Equation on chart" (and also if you want "Display R-squared value on chart"). Now you have the equation and you can easily predict the value when X is 15, you just need to substitute on the equation the X by the 15:
y = 4.0933Χ + 21.5 <=>
y = 82.8995<span>
