For the last three days, it has rained 0.13 inches, 0.08 inches, and 0.18 inches. what is the best estimate of the total rainfall?

a. 0.2 inch.

b. 0.5 inch.

c. 0.3 inch.

d. 0.4 inch.

(D) . The best estimate of the total rainfall is 0.4 inches.

Step-by-step explanation:

Here, as given in the data:

The rainfall on the first day = 0.13 inches

Now, the 'nearest tenth' estimation of 0.13  = 0.10 as ( 3 < 5)

So, the estimated rainfall on first day = 0.10 inches

The rainfall on the second  day = 0.08 inches

Now, the 'nearest tenth' estimation of 0.08  = 0.10 as ( 8 >  5)

So, the estimated rainfall on second day = 0.10 inches

The rainfall on the third  day = 0.18 inches

Now, the 'nearest tenth' estimation of  0.18  = 0.20 as ( 8 >  5)

So, the estimated rainfall on third day =0.20 inches

So, total estimated rainfall = Estimated rainfall on ( first + second + third day)

= 0.10 inches  + 0.10 inches + 0.20 inches  

= 0.40 inches

Hence,  the best estimate of the total rainfall is 0.4 inches.
