Problem Analysis

We are given two packages of pencils. One package contains 12 pencils, and the other package contains 36 more pencils than the first package. The total cost of both packages is 420 rubles. We need to determine the cost of each package.

Solution

Let's assume the cost of the first package is x rubles. Since the second package contains 36 more pencils than the first package, we can represent the cost of the second package as (x + 36) rubles.

The total cost of both packages is given as 420 rubles. We can set up the following equation:

x + (x + 36) = 420

Simplifying the equation, we get:

2x + 36 = 420

Now, let's solve for x to find the cost of the first package.

2x = 420 - 36

2x = 384

x = 384 / 2

x = 192

Therefore, the cost of the first package is 192 rubles.

To find the cost of the second package, we can substitute the value of x into the equation:

(x + 36) = (192 + 36) = 228

Therefore, the cost of the second package is 228 rubles.

Answer

Each package costs 192 rubles and 228 rubles, respectively.
