Over the past several months, the water level of a lake has been decreasing by 12% each week. If the highest water level before the decrease started was 520ft. What was the level at the end of 2 weeks?

The level was 402.7ft. at the end of two weeks.

Step-by-step explanation:

First, we need to find the amount of decrease for the first week.

520 x 0.12 = 62.4

Now, we subtract the change for the first week.

520 - 62.4 = 457.6

Next, we find the change for the second week.

457.6 x 0.12 = 54.912

Then, we subtract the change for the second week.

457.6 - 54.912 = 402.688

And we are left with our final answer that is 402.688ft. or if you wish to round to the nearest tenth, then your answer would be 402.7ft.
