Final answer:
To find the rainfall amount predicted by the Metrolist, calculate 20% of the actual rainfall of 1.5 inches, which is 0.3 inches, and then subtract it from the actual rainfall to get a prediction of 1.2 inches.
Step-by-step explanation:
The question asks how much rainfall the Metrolist predicted for Drake City, given that the actual rainfall was 1.5 inches and the prediction was 20% less than that. To find out the predicted rainfall, we need to calculate 20% of 1.5 inches and then subtract that amount from the actual rainfall.
Firstly, we find 20% of 1.5 inches by multiplying:
1.5 inches × 0.20 = 0.3 inches
Then, we subtract that amount from the actual rainfall to get the predicted rainfall:
1.5 inches - 0.3 inches = 1.2 inches
Therefore, the predicted rainfall by Metrolist was 1.2 inches.
