Jaime is a computer programmer for a company that currently has employed 100 people. Senior programmers are paid $400 more than junior programmers. If the number of Junior programmers is 2/5 of the total number of employees, and they are each paid $2000 per month, calculate the total amount of money the company pays to all the programmers per month.
Find the solution. 
The number of junior programmers in the company is 2/5*100 = 40
The total amount of money that the company pays to the Junior employees is $2000*40 = $80000
There are also 100-40 = 60 senior programmers in the company.
The senior programmers are paid $2000+$400 = $2400 each.
Senior programmers at the company receive 2400*60 = $144000 combined.
All the programmers in the company are paid a combined salary of 144000+80000 = 224000
