Question

The average annual rainfall for a town is 43.2 inches. The average monthly rainfall for the previous 9 months was 4 inches. Did the town exceed its average annual rainfall? If so, by how much?

Answer 1

Yeah, they exceeded by 0.4 inches.

Explanation:

It is given that,

→ the average monthly rainfall for the previous 9 months was 4 inches.

The monthly rainfall in 12 months,

→ 43.2 inches ÷ 12 months

→ 43.2/12

→ 3.6 inches

Then the difference will be,

→ 4 inches - 3.6 inches

→ 4 - 3.6

→ 0.4 inches

Hence, the difference is 0.4 inches.

Answer 2

• Yes, the town exceeded the average annual rainfall by 0.4 inches

Explanation:

The average annual rainfall for a town is 43.2 inches.

This is converted to average monthly as:

• 43.2 in / 12 = 3.6 in

The difference is:

• 4 in - 3.6 in = 0.4 in
