Answer 1

The total weight is given by 4.5 + 5.01 + 5.3 + 4.75 + 4.9 = 24.46

The value 24.46 is in between two whole numbers; 24 and 25

The value 24.50 onwards would have been rounded up to 25

The value 24.46 is rounded down to 24 to the nearest whole number

Answer 2

25 ounces.

Explanation:

Weight of first container=4.5 ounces

Weight of second container=5.01 ounces

Weight of third container=5.3 ounces

Weight of fourth container=4.75 ounces

Weight of fifth container=4.9 ounces

Weight of all the containers= sum of weight of all the containers

= 4.5+5.01+5.3+4.75+4.9

=24.46 ounces

24.46 is estimated to whole number as 25

Hence, 25 ounces is correct answer.
