Answer 3

Solution:

To solve this problem, we can use a system of equations to represent the given information and then solve for the prices of an apple and a pear.

Let's denote the price of one apple as A and the price of one pear as P.

We have the following information: 1. Equation 1: The total cost of an apple and a pear together is 17 rubles: - A + P = 17 2. Equation 2: The total cost of five apples and two pears is 55 rubles: - 5A + 2P = 55

We can solve these equations to find the values of A and P.

Solving the Equations:

We can use the substitution method to solve the system of equations.

From Equation 1, we can express A in terms of P: A = 17 - P

Substitute the value of A in Equation 2: 5(17 - P) + 2P = 55 85 - 5P + 2P = 55 85 - 3P = 55 -3P = 55 - 85 -3P = -30 P = -30 / -3 P = 10

Now that we have the value of P, we can find the value of A using Equation 1: A + 10 = 17 A = 17 - 10 A = 7

Conclusion:

So, the price of one apple is 7 rubles and the price of one pear is 10 rubles.
