Answer:

1100 cookies

Step-by-step explanation:

There are 3 types of cookies, the first represents 45% of the total, the second 25% and the last type there are 330. We can pose the following equation:

0.45 * x + 0.25 * x + 330 = x

solving for x:

x - 0.45 * x - 0.25 * x = 330

0.30 * x = 330

x = 330 / 0.3

x = 1100

which means that there are a total of 1100 cookies

8090 [49]
It would stay the same at 800,000 because there's nothing to show that it can be rounded.
