#### Answer

$7.22455\times10^{7}$ dollars

#### Work Step by Step

We are given that the payroll of the Green Bay Packers was approximately $72,245,500$ dollars.
Step 1: To write this number in scientific notation, we move the decimal point to the left until the original number is 7.22455.
Step 2: Since the original number was greater than 10, we moved the decimal by 7 positive places. In other words, we will raise 10 to a power of 7.
Now, we write the product of the two numbers found in Step 1 and Step 2.
$7.22455\times10^{7}$ dollars
