Calculation of the Cost of a Chocolate Bar

To calculate the cost of a chocolate bar, we can use the given information:

- Lena bought one pack of juice for 60 rubles. - Lena also bought 4 identical chocolate bars. - Lena paid a total of 200 rubles for her entire purchase. - Lena received 40 rubles in change.

Let's break down the problem step by step:

1. Calculate the total cost of the juice: - Lena bought one pack of juice for 60 rubles.

2. Calculate the total cost of the chocolate bars: - Lena paid a total of 200 rubles for her entire purchase. - Lena received 40 rubles in change. - Therefore, the total cost of the juice and chocolate bars combined is 200 - 40 = 160 rubles.

3. Calculate the cost of each chocolate bar: - Lena bought 4 identical chocolate bars. - To find the cost of each chocolate bar, we divide the total cost of the chocolate bars by the number of chocolate bars. - The cost of each chocolate bar is 160 / 4 = 40 rubles.

Therefore, each chocolate bar costs 40 rubles.

Please note that the above calculation is based on the given information and assumes that there were no additional discounts or promotions applied to the purchase.
