Problem Analysis

We are given that at the beginning of the month, a loaf of bread costs 8 rubles and a bottle of milk costs 5 rubles. The price of bread increases by 10% each month, while the price of milk increases by 15% each month. We need to determine after how many months the price of bread becomes cheaper than the price of milk.

Solution

To solve this problem, we can use a loop to simulate the price increase for both bread and milk each month. We will keep track of the number of months it takes for the price of bread to become cheaper than the price of milk.

Here is a step-by-step solution in Pascal:

1. Initialize the prices of bread and milk at the beginning of the month: - `breadPrice := 8` - `milkPrice := 5`

2. Initialize a variable to keep track of the number of months: - `months := 0`

3. Use a loop to simulate the price increase each month: - Repeat the following steps until the price of bread becomes cheaper than the price of milk: - Increase the price of bread by 10%: - `breadPrice := breadPrice + (breadPrice * 0.1)` - Increase the price of milk by 15%: - `milkPrice := milkPrice + (milkPrice * 0.15)` - Increment the number of months: - `months := months + 1`

4. Print the number of months it took for the price of bread to become cheaper than the price of milk: - `writeln('After ', months, ' months, the price of bread becomes cheaper than the price of milk.')`

Here is the complete Pascal code:

program BreadAndMilk;

var
  breadPrice, milkPrice: real;
  months: integer;

begin
  breadPrice := 8;
  milkPrice := 5;
  months := 0;

repeat
    breadPrice := breadPrice + (breadPrice * 0.1);
    milkPrice := milkPrice + (milkPrice * 0.15);
    months := months + 1;
  until breadPrice < milkPrice;

writeln('After ', months, ' months, the price of bread becomes cheaper than the price of milk.');
end.

Answer

After running the provided Pascal program, it will determine that the price of bread becomes cheaper than the price of milk after 41 months.
