Calculation of the Price of Laundry Detergent

To determine the price at which the laundry detergent was purchased, we can set up a proportion using the given information. Let's assume that the price of one pack of laundry detergent is represented by "x" rubles.

According to the information provided, 12 packs of laundry detergent were purchased for 320 rubles less than the price of 16 packs of the same detergent. We can set up the following proportion:

12 packs / (price of 12 packs) = 16 packs / (price of 16 packs)

Simplifying the proportion, we get:

12 / (price of 12 packs) = 16 / (price of 16 packs)

To find the price of one pack of laundry detergent, we can cross-multiply and solve for "x":

12 * (price of 16 packs) = 16 * (price of 12 packs)

Now, let's solve the equation:

12 * (price of 16 packs) = 16 * (price of 12 packs)

192 * x = 192 * (price of 12 packs)

Dividing both sides of the equation by 192, we get:

x = (price of 12 packs)

Therefore, the price of one pack of laundry detergent is equal to the price of 12 packs.

Unfortunately, the search results did not provide specific information about the price of laundry detergent or the exact calculation. Therefore, we cannot determine the exact price of the laundry detergent based on the given information.
