Problem Analysis

Kolya bought 3 chocolate bars for 80 rubles each and spent all his money. Lena has the same amount of money as Kolya. The question is whether Lena has enough money to buy 5 chocolate bars for 50 rubles each.

Solution

To determine if Lena has enough money to buy 5 chocolate bars for 50 rubles each, we need to compare the total cost of the chocolate bars with the amount of money Lena has.

Let's calculate the total cost of the chocolate bars that Lena wants to buy: - Number of chocolate bars: 5 - Cost per chocolate bar: 50 rubles

The total cost of the chocolate bars is calculated by multiplying the number of chocolate bars by the cost per chocolate bar: Total cost = Number of chocolate bars * Cost per chocolate bar

Now, let's calculate the total cost of the chocolate bars: Total cost = 5 * 50 rubles

To determine if Lena has enough money, we need to compare the total cost of the chocolate bars with the amount of money Lena has. If the total cost is less than or equal to the amount of money Lena has, then she has enough money to buy the chocolate bars.

Let's compare the total cost with the amount of money Lena has.

Calculation

Total cost of the chocolate bars = 5 * 50 rubles = 250 rubles

Since Lena has the same amount of money as Kolya, we need to determine the amount of money Kolya had.

Kolya bought 3 chocolate bars for 80 rubles each, so the total cost of the chocolate bars he bought is: Total cost of the chocolate bars Kolya bought = 3 * 80 rubles = 240 rubles

Therefore, Lena has the same amount of money as Kolya, which is 240 rubles.

Now, let's compare the total cost of the chocolate bars Lena wants to buy with the amount of money she has: Total cost of the chocolate bars Lena wants to buy = 250 rubles Amount of money Lena has = 240 rubles

Since the total cost of the chocolate bars Lena wants to buy (250 rubles) is greater than the amount of money she has (240 rubles), Lena does not have enough money to buy 5 chocolate bars for 50 rubles each.

Conclusion

Lena does not have enough money to buy 5 chocolate bars for 50 rubles each, even though she has the same amount of money as Kolya.
