Question 3 of 30 paul buys fruit to make smoothies. he buys 3.78 pounds of apples, 2.12 pounds of peaches, and 4.45 pounds of oranges. paul rounds each weight to the nearest tenth of a pound. about how many pounds of fruit did paul buy? (a) 10.5 pounds (b) 10.2 pounds (c) 10.4 pounds (d) 10.0 pounds 30 points

(C) 10.4 lb

Step-by-step explanation:

If Paul added each weight before adding, as you state, he got:

Apples     3.78 ⟶  3.8

Peaches   2.12 ⟶  2.1

Oranges  4.45 ⟶ 4.4

                    Total 10.3 lb

If he did it this way, he did it incorrectly, and his answer isn't in the list of options, anyway. That's because his method introduces round-off errors.

The correct way is to add the numbers as given, and then round off at the end.

Apples     3.78

Peaches  2.12

Oranges 4.45

   Total  10.35 ⟶ 10.4 lb

Note: When you drop a 5 followed by nothing, you round off to the nearest even number.
