Answer 2

Task Formulation

Let's formulate the problem and solve it step by step.

We have the following information: - 5 apples and 2 pears cost 108 rubles. - 2 apples and 2 pears cost 72 rubles.

We need to find the individual prices of apples and pears.

Problem Solving

Let's denote the cost of an apple as A and the cost of a pear as P.

From the given information, we can form the following equations: 1. 5A + 2P = 108 (Equation 1) 2. 2A + 2P = 72 (Equation 2)

Now, let's solve these equations to find the values of A and P.

Equation Solving

Subtracting Equation 2 from Equation 1: (5A + 2P) - (2A + 2P) = 108 - 72 3A = 36 A = 12

Now, we can substitute the value of A back into Equation 2 to find the value of P: 2(12) + 2P = 72 24 + 2P = 72 2P = 72 - 24 2P = 48 P = 24

Conclusion

So, the cost of an apple (A) is 12 rubles and the cost of a pear (P) is 24 rubles.
