Linear Equation for Monthly Milk Expenses
To write a linear equation for the monthly milk expenses of the family, we need to consider the fixed cost and the variable cost based on the quantity of extra milk consumed.

Fixed Cost:
- The fixed cost for milk is Rs. 500 per month.

Variable Cost:
- The variable cost depends on the quality of extra milk taken at the rate of Rs. 20 per kg.

Linear Equation:
Let x be the quantity of extra milk (in kg) consumed by the family per month.
Therefore, the total monthly expense on milk can be calculated using the equation:
Total Cost = Fixed Cost + Variable Cost
Total Cost = Rs. 500 + Rs. 20x
This equation represents the relationship between the total monthly expense on milk and the quantity of extra milk consumed by the family. The fixed cost of Rs. 500 remains constant, while the variable cost of Rs. 20 per kg depends on the quantity of extra milk consumed.
By using this linear equation, the family can calculate their total monthly expense on milk based on the quantity of extra milk they choose to consume.
