Answer 3

Calculation of Change

To calculate the change received from a purchase, we need to subtract the total cost of the items from the amount paid. In this case, the cost of each album is 90 rubles, and there is a discount of 50 rubles. So the effective cost of each album is 90 - 50 = 40 rubles.

If seven albums are purchased, the total cost would be 7 * 40 = 280 rubles.

To calculate the change received from 500 rubles, we subtract the total cost from the amount paid:

Change = Amount paid - Total cost Change = 500 - 280 Change = 220 rubles.

Therefore, the change received would be 220 rubles if seven albums are purchased for 500 rubles.
