Answer 2

Problem Analysis

We are given that the price of a whole number of rulers is unknown. However, we are given two pieces of information: - 3 rulers cost less than 18 rubles. - 8 rulers cost more than 32 rubles.

We need to determine the price of one ruler based on this information.

Solution

Let's assume the price of one ruler is x rubles.

From the given information, we can form two equations: 1. 3 rulers cost less than 18 rubles: 3x < 18. 2. 8 rulers cost more than 32 rubles: 8x > 32.

We can solve these equations to find the value of x.

Solving the Equations

Let's solve the first equation for x: 3x < 18

Divide both sides of the inequality by 3: x < 6.

Now, let's solve the second equation for x: 8x > 32

Divide both sides of the inequality by 8: x > 4.

From the two inequalities, we can conclude that the price of one ruler, x, is between 4 and 6 rubles.

Conclusion

Based on the given information, the price of one ruler is between 4 and 6 rubles.

Please note that the exact price of one ruler cannot be determined with the given information.
