Answer 2

Answer:

The times Americans spent with digital media in year 2017 is found to be 6 hours per day.

Step-by-step explanation:

We are given that the time Americans spent with digital media in 2018 was found to be: 6.3 hours per day.

We are also given that this data was 5% more than what the usage per day was in the year 2017.

So, Let the previous digital media usage be $x$ in 2017,

So, according to the given problem, we get:

$x+\frac{5}{100}x=6.3$

Taking the LCM of denominators and simplifying, we get:

$\frac{5x+100x}{100}=6.3$

or we can say:

$\frac{105x}{100}=6.3$

Seperating the variables, we get:

$x=\frac{6.3\times 100}{105}$

Simplifying it, we get:

$x=6$

Therefore, the Americans spent 6 hours per day on digital media in 2017.
