Answer:
Step-by-step explanation:
Riley collected rain for several weeks in rain gauge.
He collected 1.48 inches the first week.
He collected half that much the second week. This means that he collected 0.5 × 1.48 = 0.74 inches
He collected one inch the third week. The total amount of water in inches, collected already is
1.48 + 0.74 + 1= 3.22 inches.
To determine much more rain that Riley need to collect before he has five inches, we will subtract the amount already collected from 5. It becomes
5 - 2.22 = 1.78 inches
