Problem Analysis

We are given the information that the price of a pen is 6 times less than the price of a photo album. We also know that 7 pens were purchased for a total of 420 rubles. We need to find the price of the photo album and create an equation to solve the problem.

Solution

Let's assume the price of the photo album is x rubles. Since the price of the pen is 6 times less than the price of the album, the price of the pen can be represented as x - 6x or -5x rubles.

We are also given that 7 pens were purchased for a total of 420 rubles. We can set up the equation:

7 * (-5x) = 420

Simplifying the equation:

-35x = 420

Dividing both sides of the equation by -35:

x = -420 / -35

Simplifying further:

x = 12

Therefore, the price of the photo album is 12 rubles.

Answer

The price of the photo album for photographs is 12 rubles.
