Answer:
42-38
42 + (-38)
-38+42
Step-by-step explanation:
In all of these expressions, the 38 has to be negative because that is what you're taking away from the 48. When you have -(- it turns into a +.
In -42 + 38 the 42 is negative, but that is Emma's total amount so it's positive
With -42 -(-38) they did the just added those two together which would make the 42 still negative and the 38 positive.
THen with 42 + 38 the 38 is being subtracted from what she has so you would not add 38 to her total.

Answer:
7.1%
Step-by-step explanation:
The formula for percentage relative change =
[Final value - Initial value/Initial value] × 100
From the above question
Initial value = 42 %
Final value = 45%
= 45 - 42/ 42 × 100
= 3/42 × 100
= 7.1428571429 %
Therefore, approximately to the nearest tenth, the percentage relative change = 7.1%
