Household Contribution to Food Spending

A research study analyzed the weekly spending habits of various households in a neighborhood, focusing on food, entertainment, and utilities. The findings were summarized as follows:

• Household A: $150 on food, $100 on entertainment, $50 on utilities.
• Household B: $180 on food, $120 on entertainment, $60 on utilities.
• Household C: $200 on food, $80 on entertainment, $40 on utilities.
• Household D: $170 on food, $110 on entertainment, $70 on utilities.

If the average weekly spending on food among these households is calculated, which household contributes the most to this average?
