Problem Analysis

We are given the prices of three apples, four pears, and one peach, as well as the prices of one apple, four pears, and one peach. We need to determine the price of one apple, one pear, and one peach, as well as the price of two apples.

Solution

Let's assign variables to the unknown prices: - Let A be the price of one apple. - Let P be the price of one pear. - Let C be the price of one peach.

From the given information, we can form two equations: 1. 3A + 4P + C = 40 (Equation 1) 2. A + 4P + C = 32 (Equation 2)

To find the price of one apple, one pear, and one peach, we need to solve these equations simultaneously. We can subtract Equation 2 from Equation 1 to eliminate the variable A:

(Equation 1) - (Equation 2): 3A + 4P + C - (A + 4P + C) = 40 - 32 2A = 8 A = 4

Now that we have the price of one apple, we can substitute this value back into Equation 2 to find the price of one pear and one peach:

4 + 4P + C = 32 4P + C = 28

To find the price of two apples, we can multiply the price of one apple by 2:

2A = 2 * 4 = 8

Therefore, the price of one apple, one pear, and one peach is 4 rubles, and the price of two apples is 8 rubles.

Answer

The price of one apple, one pear, and one peach is 4 rubles, and the price of two apples is 8 rubles.
