Answer 2

Problem Analysis

We are given that there are three large packets and four small packets of cookies, and the total weight of all the cookies is 550 grams. We need to find the weight of the cookies in a small packet if it contains half the amount of cookies as a large packet.

Solution

Let's assume the weight of the cookies in a large packet is L grams and the weight of the cookies in a small packet is S grams.

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

Equation 1: 3L + 4S = 550 (since the total weight of all the cookies is 550 grams)

Equation 2: S = (1/2)L (since the weight of the cookies in a small packet is half the weight of the cookies in a large packet)

To solve this system of equations, we can substitute Equation 2 into Equation 1:

3L + 4((1/2)L) = 550

Simplifying the equation:

3L + 2L = 550

5L = 550

Dividing both sides by 5:

L = 110

Now, we can substitute the value of L back into Equation 2 to find the weight of the cookies in a small packet:

S = (1/2)(110)

S = 55

Therefore, the weight of the cookies in a small packet is 55 grams.

Answer

The weight of the cookies in a small packet is 55 grams.
