Answer 2

To solve this problem, we need to find the cost per kilogram of apples and pears. Let's break down the information given:

- 7 kg of apples and 4 kg of pears were purchased for a total of 68 UAH. - 5 kg of apples are more expensive than 2 kg of pears by 17 UAH.

Step 1: Finding the cost per kilogram of apples and pears

Let's assume the cost per kilogram of apples is A UAH and the cost per kilogram of pears is P UAH.

From the given information, we can set up the following equations:

Equation 1: 7A + 4P = 68 (since 7 kg of apples and 4 kg of pears were purchased for 68 UAH)

Equation 2: 5A = 2P + 17 (since 5 kg of apples are more expensive than 2 kg of pears by 17 UAH)

Step 2: Solving the equations

To solve these equations, we can use substitution or elimination method. Let's use the substitution method.

From Equation 2, we can express A in terms of P:

5A = 2P + 17 A = (2P + 17) / 5

Now, substitute this value of A into Equation 1:

7((2P + 17) / 5) + 4P = 68

Simplify the equation:

(14P + 119) / 5 + 4P = 68 14P + 119 + 20P = 340 34P = 221 P ≈ 6.5

Now, substitute the value of P back into Equation 1 to find A:

7A + 4(6.5) = 68 7A + 26 = 68 7A = 42 A = 6

Step 3: Final answer

Therefore, the cost per kilogram of apples is approximately 6 UAH, and the cost per kilogram of pears is approximately 6.5 UAH.

So, 1 kg of apples costs 6 UAH, and 1 kg of pears costs 6.5 UAH.

Please note that the values of A and P are approximations, as the original problem did not provide exact values.
