Answer 1

Answer:

19,500

Step-by-step explanation:

Average monthly earnings of 4 members [(a+b+c+d)/4]=18,500

Total monthly earning of 4 members (a+b+c+d) = 74,000(ie.18,500×4)

When a new member joins,

Average monthly earnings of 5 members [(a+b+c+d+e)/5] = 18,700

Total monthly earnings of 5 members (a+b+c+d+e) = 93,500(ie. 18,700×5)

Monthly earning of new member = 93,500-74,000

=19,500
