Calculating the Number of Letters Received Before Lunch

To calculate the number of letters received before lunch, we can use the information provided and apply basic arithmetic.

Given: - The post office received a certain number of letters before lunch. - After lunch, they received an additional 79 letters. - All the letters were divided into 3 bags, with 56 letters in each bag.

Calculation

Let's denote the number of letters received before lunch as "x". - After lunch, the total number of letters becomes "x + 79". - Since all the letters were divided into 3 bags with 56 letters in each bag, the total number of letters can also be expressed as 3 * 56.

So, we have the equation: x + 79 = 3 * 56

Now, let's solve for "x": x = (3 * 56) - 79

Solution

Let's calculate the value of "x": x = (3 * 56) - 79 x = 168 - 79 x = 89

Therefore, the number of letters received before lunch is 89.
