The number of new members that needed to be signed up at the end of one year.
Answer to Problem 22PPS
The number of new members that needed to be signed up at the end of one year is 193.
Explanation of Solution
Given:
The number of new members that needed to be signed up initially is 850. The number of new members to be signed up decrease by 11.6 % every month.
Concept used:
The formula of reduction rate over a time period is given by,
Calculation:
The number of new members that remain to be signed up after 12 months is calculated as,
Conclusion:
Hence, the number of new members that needed to be signed up at the end of one year is 193.
