First find Todd's contribution by doubling the boss's contribution: $15 * 2 = $<<15*2=30>>30
Now subtract Todd and the boss's contributions to find out how much still needs to be paid: $100 - $30 - $15 = $<<100-30-15=55>>55
Now divide the remaining cost by the number of employees to find the cost per employee: $55 / 5 employees = $<<55/5=11>>11/employee
