A politician's support grew from 42% by 3 percentage points to 45%. What percent (relative) change is this? Round your answer to the nearest tenth of a percent.

Respuesta :

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%
