Answer 1

The former number of enrollees was 1423135

Explanation:

Current number of enrollments in Health Maintenance Organizations in Illinois in recent year = 2462170

Now, it is found that this number is a result of 42.2% increase from the last year.

So, Previous year the number of enrollments is 42.2% less than the recent number of enrollments

Now, Former number of enrollments = 2462170 - 42.2% of 2462170

= 2462170 - 0.422 × 2462170

= 2462170 - 1039035.74

= 1423134.26 ≈ 1423135

Hence, The former number of enrollees was 1423135
