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
