Answer:
(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 ⟶ <u> 4.4
</u>
Total 10.3 lb
If he did it this way, he did it <em>incorrectly</em>, 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 <em>at the end</em>.
Apples 3.78
Peaches 2.12
Oranges <u> 4.45</u>
Total 10.35 ⟶ 10.4 lb
Note: When you drop a 5 f<em>ollowed by nothing</em>, you round off to the <em>nearest even number</em>.
Well,
2.5(18) = 45
45 = 45
It's as simple as that. n=18 is the solution to the problem.
