Answer:
The president's approval rating in 2014 is 60.9%
Step-by-step explanation:
The parameters given are;
President's approval rating in 2015 = 42%
President's approval rating in 2015 = 31% less than 2014 president's approval rating
Therefore, whereby the president's approval rating in 2014 = x, we have;
42% = x - 31% of x = x - 0.31·x = 0.69·x
Hence, x% = 42% ÷ 0.69 = 60.8696 ≈ 60.9%
The president's approval rating in 2014 = 60.9%.
his approval rating in 2014 is 60.9%
- The calculation is as follows:
Here we assume the president's approval rating in 2014 = x
So,
42% = x - 31% of x
= x - 0.31·x
= 0.69·x
Now
Hence, x% [tex]= 42\% \div 0.69[/tex] = 60.8696 ≈ 60.9%
