Calculation of the Total Cost of the Purchase

To calculate the total cost of the purchase, we need to multiply the number of each type of chocolate bar by its respective price and then sum up the individual costs.

Given: - 60 chocolate bars in total - Three types of chocolate bars with weights of 50g, 40g, and 30g - Prices per bar: 24 rubles for the first type, 21 rubles for the second type, and 18 rubles for the third type - Total weight of the purchase: 2.5 kg

Let's calculate the total cost step by step:

1. Calculate the total weight of each type of chocolate bar: - Number of bars of the first type: 60 - Weight of each bar of the first type: 50g - Total weight of the first type of chocolate bars: 60 * 50g = 3000g = 3kg

- Number of bars of the second type: 60 - Weight of each bar of the second type: 40g - Total weight of the second type of chocolate bars: 60 * 40g = 2400g = 2.4kg

- Number of bars of the third type: 60 - Weight of each bar of the third type: 30g - Total weight of the third type of chocolate bars: 60 * 30g = 1800g = 1.8kg

2. Calculate the total cost for each type of chocolate bar: - Total cost of the first type of chocolate bars: 60 * 24 rubles = 1440 rubles - Total cost of the second type of chocolate bars: 60 * 21 rubles = 1260 rubles - Total cost of the third type of chocolate bars: 60 * 18 rubles = 1080 rubles

3. Calculate the total cost of the purchase by summing up the costs of each type of chocolate bar: - Total cost of the purchase = Total cost of the first type + Total cost of the second type + Total cost of the third type - Total cost of the purchase = 1440 rubles + 1260 rubles + 1080 rubles = 3780 rubles

Therefore, the total cost of the purchase is 3780 rubles.
