Mrs. Anna has ten (10) broilers and she feed one of them 20 kg of broiler mash each week. Find the cost of feeding ten (10) broilers for five (5) weeks.

The problem states that 20 kg of broiler mash costs N$ 110.00. The phrasing "she feed one of them 20 kg of broiler mash each week" is ambiguous. However, to match one of the provided options, we assume that 20 kg is the total amount of mash fed to all ten broilers each week. Therefore, the cost to feed ten broilers for one week is N$ 110.00.

To find the total cost, multiply the weekly cost by the number of weeks.

$\text{Total cost} = \text{N\$ } 110.00 \times 5$ $\text{Total cost} = \text{N\$ } 550.00$

Comparing this to the given options:
A. N$200 B. N$550 C. N$110 D. N$1550

The calculated total cost matches option B.

The final answer is \boxed{\text{B. N\550}}$.
