Number of men with lower incomes
=
58 x 16
= 10
Number of men with higher incomes
= 16 - 10
= 6
Total monthly incomes
= 10 u + 18 u
= 28 u
28 u = 47600
1 u = 47600 ÷ 28 = 1700
Difference between the higher monthly income and the lower monthly income
= 3 u - 1 u
= 2 u
= 2 x 1700
= $3400
Answer(s): $3400
