Answer 3

Calculation of Lena's Money

To calculate how much money Lena had initially, we need to consider the following information: - Lena bought 4 packs of ice cream for 15 rubles each. - She spent twice as much as she had left.

Let's break down the calculation step by step:

1. Calculate the total amount spent on ice cream: - Lena bought 4 packs of ice cream for 15 rubles each. - So, the total amount spent on ice cream is 4 * 15 = 60 rubles.

2. Calculate the amount Lena had left: - Lena spent twice as much as she had left. - Let's assume she had x rubles left. - According to the given information, she spent twice as much as she had left, which means she spent 2x rubles. - So, the equation becomes: 2x = 60. - Solving the equation, we find that x = 60 / 2 = 30 rubles.

Therefore, Lena initially had 30 rubles.

Calculation of Candy and Lollipop Purchases

Now, let's calculate how many candies and lollipops Lena can buy with the remaining money.

1. Calculate the number of candies Lena can buy: - The price of each candy is 2 rubles and 50 kopeks. - Lena has 30 rubles. - To convert kopeks to rubles, we divide the price by 100: 50 kopeks = 50 / 100 = 0.5 rubles. - So, the price of each candy is 2 + 0.5 = 2.5 rubles. - To calculate the number of candies Lena can buy, we divide the remaining money by the price of each candy: 30 / 2.5 = 12 candies.

2. Calculate the number of lollipops Lena can buy: - The price of each lollipop is 50 kopeks. - Lena has 30 rubles. - To convert kopeks to rubles, we divide the price by 100: 50 kopeks = 50 / 100 = 0.5 rubles. - So, the price of each lollipop is 0.5 rubles. - To calculate the number of lollipops Lena can buy, we divide the remaining money by the price of each lollipop: 30 / 0.5 = 60 lollipops.

Therefore, Lena can buy 12 candies and 60 lollipops with the remaining money.
