Question

За три пакета молока и пачку творога заплатили 85 р 50 коп. какова цена пакета молока и пачки творога, если пакет молока дороже пачки творога на 4 р 5 коп?

Answer 1

Х-пачка творога
х+4,5-пакет молока
(х+4,5)3+х=85,5
3х+13,5+х=85,5
4х+13,5=85,5
4х=85,5-13,5
4х=72
х=72:4
х=18


18 р. - пачка творога
18р. + 4р. 50 коп. =22р. 50 коп. - пакет молока

Answer 2

Problem Analysis

We are given that the total cost of three packets of milk and one packet of cottage cheese is 85 rubles and 50 kopeks. We are also told that the price of one packet of milk is 4 rubles and 5 kopeks more than the price of one packet of cottage cheese. We need to find the individual prices of the milk and cottage cheese packets.

Solution

Let's assume the price of one packet of cottage cheese is x rubles and y kopeks. Since the price of one packet of milk is 4 rubles and 5 kopeks more than the price of one packet of cottage cheese, the price of one packet of milk can be expressed as (x + 4 rubles) and (y + 5 kopeks).

According to the given information, the total cost of three packets of milk and one packet of cottage cheese is 85 rubles and 50 kopeks. We can write this as an equation:

3 * (x + 4) rubles + (y + 5) kopeks + x rubles + y kopeks = 85 rubles + 50 kopeks

Simplifying the equation, we get:

3x + 12 rubles + y + 5 kopeks + x rubles + y kopeks = 85 rubles + 50 kopeks

Combining like terms, we have:

4x + 2y + 17 rubles + 6 kopeks = 85 rubles + 50 kopeks

Subtracting 17 rubles and 6 kopeks from both sides, we get:

4x + 2y = 85 rubles + 50 kopeks - 17 rubles - 6 kopeks

Simplifying further, we have:

4x + 2y = 68 rubles + 44 kopeks

To solve this equation, we need another equation. However, we don't have any additional information to form a second equation. Therefore, we cannot determine the exact prices of the milk and cottage cheese packets with the given information.

However, we can express the prices in terms of variables:

The price of one packet of milk = x + 4 rubles and y + 5 kopeks The price of one packet of cottage cheese = x rubles and y kopeks

Please note that these expressions are in terms of variables and cannot be simplified further without additional information.

Conclusion

The exact prices of the milk and cottage cheese packets cannot be determined with the given information. However, we have expressed the prices in terms of variables.
