Answer 2

Calculation of the Cost of Bread and Milk

To calculate the cost of one loaf of bread, we need to consider the given information. We know that for 3 loaves of bread and 2 cups of milk, the total cost is 20 coins. Additionally, we are told that one loaf of bread is cheaper than one cup of milk by 5 coins.

Let's assume the cost of one loaf of bread is x coins. Since one loaf of bread is cheaper than one cup of milk by 5 coins, the cost of one cup of milk would be x + 5 coins.

Now, let's calculate the total cost using the given information:

- The cost of 3 loaves of bread would be 3x coins. - The cost of 2 cups of milk would be 2(x + 5) coins.

According to the problem, the total cost of 3 loaves of bread and 2 cups of milk is 20 coins. Therefore, we can set up the following equation:

3x + 2(x + 5) = 20

Now, let's solve this equation to find the value of x, which represents the cost of one loaf of bread.

Solving the Equation

Expanding the equation, we get:

3x + 2x + 10 = 20

Combining like terms, we have:

5x + 10 = 20

Subtracting 10 from both sides of the equation, we get:

5x = 10

Dividing both sides of the equation by 5, we find:

x = 2

Therefore, the cost of one loaf of bread is 2 coins.

Conclusion

Based on the given information, the cost of one loaf of bread is 2 coins, and one cup of milk costs 7 coins (2 + 5).

Please note that the information provided is based on the given problem statement and calculations.
