Fa Billy a ne a thapiwa la ntlha, o ne a duelwa tuelo ya $10 ka ura.  Morago ga dikgwedi di le 2, o ne a tlhatlosiwa madi a a neng a a duelwa ka $0.50 ka ura.  Mo segopotso sa gagwe sa ntlha kwa tirong, o ne a tlhatlosiwa madi a a neng a a duelwa ka $1.00 ka ura.  Sally o sa tswa simolola go bereka kwa kgwebong e e farologaneng, mme tuelo ya gagwe ya tshimologo e kwa godimo ga ya ga Billy ka $0.50 ka ura.

A company's HR hires 20 new employees every month to add to its total workforce. If the company's initial employee number is 200, and each employee is paid a $4000 salary per month, calculate the total amount of money the company pays to its employees after three months?
Billy o na le tuelo ya $10+0.50+$1.00=$<<10+0.5+1=11.50>>11.50 ka ura.
Sally o duelwa $0.50 go feta ka ura go feta tuelo ya ntlha ya ga Billy, e leng palogotlhe ya $10+$0.50=$<<10+0.5=10.50>>10.50 ka ura.
Fa Billy a bereka diura di le 20, o tla duelwa 20*$11.50=$<<20*11.5=230>>230.
Fa Sally a bereka diura di le 20, o tla duelwa 20*$10.50=$<<20*10.50=210>>210.
Ka jalo, fa bobedi ba bona ba bereka diura di le 20, Billy o tla duelwa $230-$210=$20 go feta.

If each month the company hire 20 new employees, the total number of employees in the company in the first month is 200 employees + 20 employees = <<200+20=220>>220 employees
If each employee is paid $4000 per month, the total amount of money paid by the employee to its workers in the first month is 220 employees * $4000/employee = $<<220*4000=880000>>880000
In the second month, 20 more workers are hired, bringing the total number of employees to 220 employees + 20 employees = 240 employees
The company pays a total of 240 employees * $4000/employee = $<<240*4000=960000>>960000 in wages for its employees in the second month.
When an additional 20 workers are hired in the third month, the total number of workers become 240 employees + 20 employees = <<240+20=260>>260 employees
In total, the company 260 employees * $4000/employee = $<<260*4000=1040000>>1040000 in wages on the third month.
The total amount of money the company pays to all its employees in the three months is $1040000 + $960000 + $880000 = <<1040000+960000+880000=2880000>>2880000
