Answer 1

The answer is 0.56in.

Explanation:

The average water level of the last 4 days

= Sum of water levels for 4 days / 4

= (4.5 - 3 /8 - 2.75 + 6/7) / 4

= 0.558

= 0.56 in.

Answer 2

see below

Explanation:

average water level of the last 4 days = total of last 4 days / 4 days

= ( 4.5 in + -3 /8in + -2.75 in + 6/7 in ) / 4

= ( 4 1/2 - 3/8 - 2 3/4 + 6/7 ) / 4

= ( 2 13/56) / 4

= 125/224 in

= 0.558 in (rounded)
