Answer 2

Problem Analysis

We are given two scenarios involving a jar filled with honey. In the first scenario, the jar is completely filled with honey and weighs 850g. In the second scenario, the jar is filled halfway and weighs 550g. We need to find the weight of the empty jar.

Solution

Let's assume the weight of the empty jar is x grams.

In the first scenario, when the jar is completely filled with honey, the total weight is 850g. This includes the weight of the honey and the weight of the jar. So we can write the equation as:

x + weight of honey = 850g

In the second scenario, when the jar is filled halfway, the total weight is 550g. This includes the weight of the honey and the weight of the jar. So we can write the equation as:

x + (weight of honey / 2) = 550g

To solve this system of equations, we can use the method of substitution.

From the second equation, we can isolate the weight of the honey:

weight of honey = (550g - x) * 2

Substituting this value into the first equation, we get:

x + (550g - x) * 2 = 850g

Simplifying the equation:

x + 1100g - 2x = 850g

1100g - x = 850g

x = 1100g - 850g

x = 250g

Therefore, the weight of the empty jar is 250g.

Answer

The weight of the empty jar is 250g.
