First 12 weeks
- $20,000 (new sink) + $540 per week + $300 (grom 20 dogs) =$20,840
After 12 weeks
- $20,000 (new sink) + $540 per week + $900 (grom 60 dogs) = $21,440
Calculate the total profit:
- $35 per dog
- First 12 weeks: $700
- After 12 weeks: $2100
Finally, calculate how much it will take this new employee to start getting a profit:
- Profit during the first 12 weeks: $8,400
- Costs during the first 12 weeks: $20,840 + 10,080
- Total balance: $21,920 - $8,400 = $13,520
Profit after the first twelve weeks
- Profits per week: $2100
- Costs: $13,520 + $1,440 per week
After 20 weeks
- Profits per week: $42,000
- Costs: $13,520 + $28,800 = $42,320
- Total balance: $42,320 - $42,000 = $300
This means that by the end of week 32 the employee has almost paid all the money and it is expected by week 33 he can start to make a profit.
