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%
The answer is C!
