Answer 3

Calculation of the Price per Package of Laundry Detergent

To calculate the price per package of laundry detergent, we can use the information provided: 12 packages were purchased for 320 rubles, which is less than the price for 16 packages of the same detergent.

Let's assume the price per package of detergent is x rubles.

According to the given information, we can set up the following equation:

12x = 320

To find the price per package, we need to solve for x.

Dividing both sides of the equation by 12, we get:

x = 320 / 12

Simplifying the equation, we find:

x = 26.67 rubles

Therefore, the price per package of laundry detergent is 26.67 rubles.
