Number of men with lower incomes
=
35 x 10
= 6
Number of men with higher incomes
= 10 - 6
= 4
Total monthly incomes
= 6 u + 16 u
= 22 u
22 u = 55000
1 u = 55000 ÷ 22 = 2500
Difference between the higher monthly income and the lower monthly income
= 4 u - 1 u
= 3 u
= 3 x 2500
= $7500
Answer(s): $7500
