An insurance company has 10,276 subscribers who have a chiropractic benefit of $500.00 per calendar year. At the end of the year it was determined that 3,221 subscribers maxed out their $500.00 benefit. What is the rate, expressed in a percent (round to 2 digits after the decimal) who have maxed out their chiropractic benefit for the year?

100 3,221/10,276 = ? * 100

To find the rate of subscribers who have maxed out their chiropractic benefit, you need to divide the number of subscribers who maxed out by the total number of subscribers, and then multiply the result by 100 to express it as a percentage.

Step 1: Calculate the rate
Rate = (Number of subscribers who maxed out / Total number of subscribers) * 100

Step 2: Substitute the given values into the formula
Number of subscribers who maxed out = 3,221
Total number of subscribers = 10,276

Rate = (3,221 / 10,276) * 100

Step 3: Perform the calculation
Rate = 0.31398647547 * 100

Step 4: Round the result to two decimal places
Rate ≈ 31.40%

Therefore, approximately 31.40% of subscribers have maxed out their chiropractic benefit for the year.
