Answer 2

Problem 1: Buying Paints and Pencils

To solve this problem, we need to find the price of one box of paints and one box of pencils. Let's assume the price of one box of paints and one box of pencils is x rubles.

The total cost of the paints is given as 640 rubles. Since they bought 4 boxes of paints, we can write the equation:

4 * x = 640

Simplifying the equation, we find:

x = 640 / 4 = 160 rubles

Therefore, the price of one box of paints and one box of pencils is 160 rubles.

Now, we need to find out how much more they paid for the pencils compared to the paints. They bought 6 boxes of pencils, so the total cost of the pencils is:

6 * x = 6 * 160 = 960 rubles

To find the difference in cost, we subtract the cost of the paints from the cost of the pencils:

960 - 640 = 320 rubles

Therefore, they paid 320 rubles more for the pencils than for the paints.

Problem 2: Number of Maps in Each Bag

To solve this problem, we need to find the number of maps in each bag. Let's assume the number of maps in each bag is x.

The cost of the maps in one bag is given as 120 rubles, and the cost of the maps in the other bag is given as 240 rubles. We can write the equations:

x * 120 = 120 rubles x * 240 = 240 rubles

Simplifying the equations, we find:

x = 1 (since 120 / 120 = 1) x = 1 (since 240 / 240 = 1)

Therefore, there is 1 map in each bag.
