Calculating the Cost of Color Paper and Cardboard

To calculate the cost difference between 9 sheets of color paper and 3 sheets of colored cardboard, we can use the given prices: - One sheet of color paper costs 4 rubles. - One sheet of colored cardboard costs 10 rubles.

Cost of 9 Sheets of Color Paper

The cost of 9 sheets of color paper can be calculated as follows: ``` Cost of 9 sheets of color paper = 9 * 4 = 36 rubles ``` The cost of 9 sheets of color paper is 36 rubles.

Cost of 3 Sheets of Colored Cardboard

The cost of 3 sheets of colored cardboard can be calculated as follows: ``` Cost of 3 sheets of colored cardboard = 3 * 10 = 30 rubles ``` The cost of 3 sheets of colored cardboard is 30 rubles.
