From the graph, let's identify the expenditure on rice for Latvia (the blue bar). Based on the provided image, the rice expenditure for Latvia appears to be around 150 Euros.

Step-by-step approach:

1. Total expenditure on rice by subpopulation:

   • Number of people in subpopulation = 5,000.
   • Each family has 4 members, so there are $\frac{5000}{4} = 1250$ households.
   • Expenditure on rice per household per month = 150 Euros (from the graph).
   • Total expenditure on rice by all households = $1250 \times 150 = 187,500$ Euros.

2. Expenditure per individual:

   • Since the total population is 5,000 people, the total expenditure divided by the number of people gives the average spent per individual.
   • $\frac{187,500 \, \text{Euros}}{5000 \, \text{people}} = 37.5 \, \text{Euros per person}$.

3. Percentage of total expenditure per individual:

   • Total expenditure on rice = 187,500 Euros.
   • Average expenditure per person = 37.5 Euros.
   • Percentage $= \frac{37.5}{187,500} \times 100 \approx 0.02\%$.

Thus, on average, each individual in this subpopulation spends approximately 0.02% of the total expenditure on rice.
