Calculate the total expenditure and total eggs produced for a poultry farm over an 18-month laying period, given initial costs, feed costs, and laying rates.

Step 1: Calculate the cost of purchasing the chicks.
Number of chicks = 500
Cost per chick = Shs. 80
Cost of chicks = $500 \times \text{Shs. } 80 = \text{Shs. } 40,000$

Step 2: Identify the expenditure for the first six months.
Expenditure for the first six months = Shs. 228,000

Step 3: Calculate the cost of feed during the laying period.
Laying period = 18 months
Days in one month = 30 days
Total days in laying period = $18 \text{ months} \times 30 \text{ days/month} = 540 \text{ days}$
Feed consumption = 1 bag per day
Cost per bag = Shs. 1,000
Cost of feed = $540 \text{ days} \times 1 \text{ bag/day} \times \text{Shs. } 1,000/\text{bag} = \text{Shs. } 540,000$

Step 4: Calculate the total expenditure for the entire period.
Total expenditure = Cost of chicks + First six months expenditure + Cost of feed during laying period
Total expenditure = Shs. $40,000 + \text{Shs. } 228,000 + \text{Shs. } 540,000 = \text{Shs. } 808,000$
