Number of men with lower incomes
=
58 x 24
= 15
Number of men with higher incomes
= 24 - 15
= 9
Total monthly incomes
= 15 u + 45 u
= 60 u
60 u = 114000
1 u = 114000 ÷ 60 = 1900
Difference between the higher monthly income and the lower monthly income
= 5 u - 1 u
= 4 u
= 4 x 1900
= $7600
Answer(s): $7600
