predicted 37.5% less rain than that. How much rain did the meteorologist predict for
Peakstown?

inches

Answer 1

To find the amount of rain the meteorologist predicted, we calculate 37.5% of the actual rainfall of 3.2 inches, which is 1.2 inches, and subtract it from the actual rainfall, resulting in a prediction of 2 inches of rain.

Step-by-step explanation:

The student is asking how much rain the meteorologist predicted for Peakstown when the actual amount of rain was 3.2 inches, which was 37.5% more than the predicted amount. To find the predicted amount, we will calculate 37.5% of the actual rainfall and subtract that from the actual rainfall.

First, find 37.5% of 3.2 inches:

1. Convert the percentage to decimal form: 37.5% = 0.375.
2. Multiply this decimal by the actual rainfall: 0.375 x 3.2 inches = 1.2 inches.
3. Subtract the above amount from the actual rainfall to find the predicted amount: 3.2 inches - 1.2 inches = 2 inches.

The meteorologist predicted 2 inches of rain for Peakstown.

Answer 2

Step-by-step explanation:

So what I would start with is laying out the important information.

We do know that Peakstown had 3.2 inches of rain and the meteorologist predicted for 37.5% less rain than that.

So do 3.2 - 37.5/100 ( putting something over 100 is the same as doing a percent sign)

3.2 - 37.5/100

Divide 37.5 by the 100 to get

3.2-0.375

Then just simply do the subtraction

3.2-0.375= 2.825

So if I'm correct the answer should be 2.825 inches or 2 33/40 inches

(I'm sorry if it is incorrect, I believe that the problem is apart of algebraic expressions or solving for x if that helps)
