Problem Analysis

We are given that the total cost of a ruler and a pencil is 33 rubles. The price of the ruler is 3/8 of the price of the pencil. We need to find the individual prices of the ruler and the pencil.

Solution

Let's assume the price of the pencil is x rubles. According to the given information, the price of the ruler is 3/8 of the price of the pencil.

The equation representing the total cost of the ruler and the pencil is:

x + (3/8)x = 33

Simplifying the equation:

(11/8)x = 33

To find the value of x, we can multiply both sides of the equation by the reciprocal of (11/8), which is (8/11):

x = (8/11) * 33

Calculating the value of x:

x = 24

Therefore, the price of the pencil is 24 rubles.

To find the price of the ruler, we can substitute the value of x into the equation:

(3/8) * 24 = 9

Therefore, the price of the ruler is 9 rubles.

Answer

The pencil costs 24 rubles and the ruler costs 9 rubles.
