after the price increase to 35cents the cost of the company of posting 1200 letters was dollars 399. calculate the percentage discount that the company was given in 2006

Answer 1

In order to calculate the percentage discount, we need to know the original cost of posting 1200 letters before the price increase.

Let's assume the original cost per letter was x dollars.

Before the price increase, the total cost of posting 1200 letters would be:
Total cost = (Original cost per letter) x (Number of letters)
Total cost = x * 1200

After the price increase, the total cost of posting 1200 letters is given as 399 dollars.

We can now set up an equation using the information given:
399 = 0.35 * 1200

Simplifying the equation:
399 = 420

This means that the equation is not solvable without additional information.
