Problem Analysis

We are given that a store received a shipment of cookies. On the first day, they sold 52 kg of cookies, and on the second day, they sold 1.3 times less than on the first day. We need to determine how many kilograms of cookies were brought to the store if they sold 1/3 of the total shipment in two days.

Solution

Let's assume that the total shipment of cookies brought to the store is represented by the variable x (in kg).

On the first day, they sold 52 kg of cookies, so the remaining amount of cookies is x - 52.

On the second day, they sold 1.3 times less than on the first day, which is equivalent to selling 1.3 * 52 kg of cookies. Therefore, the amount of cookies sold on the second day is 1.3 * 52 = 67.6 kg.

The total amount of cookies sold in two days is 1/3 of the total shipment, which is (52 + 67.6) = (x/3).

To solve for x, we can set up the equation:

(52 + 67.6) = (x/3)

Let's solve this equation to find the value of x.

Calculation

(52 + 67.6) = (x/3)

Simplifying the equation:

119.6 = (x/3)

Multiplying both sides of the equation by 3:

3 * 119.6 = x

x = 358.8

Therefore, the store received 358.8 kg of cookies.

Answer

The store received 358.8 kg of cookies.
