Question

1. on monday, 3.11 inches of rain fell and on tuesday, 0.81 inch of rain fell. on wednesday, twice as much rain fell as on tuesday. how much rain fell during the 3 - day period?

Explanation:

Step1: Find Wednesday's rain

Tuesday's rain is 0.81 inch. Wednesday's rain is twice Tuesday's, so $0.81\times2 = 1.62$ inches.

Step2: Sum all three days' rain

Monday: 3.11, Tuesday: 0.81, Wednesday: 1.62. Total = $3.11 + 0.81 + 1.62$.
Calculate: $3.11+0.81 = 3.92$; $3.92 + 1.62 = 5.54$.

Answer:

5.54 inches
