Number of men with lower incomes
=
37 x 14
= 6
Number of men with higher incomes
= 14 - 6
= 8
Total monthly incomes
= 6 u + 24 u
= 30 u
30 u = 87000
1 u = 87000 ÷ 30 = 2900
Difference between the higher monthly income and the lower monthly income
= 3 u - 1 u
= 2 u
= 2 x 2900
= $5800
Answer(s): $5800
