The histograms show the number of new subscribers in one month by age group for three newspaper. which statement is best support
ed by the data in the histograms?
A: the chronicle had more new subscribers for each age group than either the times the daily.
B: there were 1000 fewer new subscribers in the 20-29 and the 30-39 age groups combined for the chronicle than there were in these same age groups for the times and the daily combined
C: the chronicle had exactly 50,500 new subscribers for all age groups combined
D: there were three times as many new subscribers in the 20-29 and the 30-39 age groups combined for the chronicle than in the 20-29 age group for the times.

Using the given information and what we know about linear equations, we will find the sketch below.
<h3>How to sketch a graph?</h3>Here we need to analyze each part separately.
In a coordinate axis where the y-axis represents distance and the x-axis represents time, we will have that:
First, we know that he rides for 30 minutes at a given speed, this will be represented with an increasing linear function.
Then he stops for 20 minutes, this is represented with a horizontal line.
Finally, he returns the motion, but slower than before, so the slope of this line will be smaller than the first one.
So for 0 to 30 we have an increasing linear equation, then for 30 to 50 we have a constant horizontal line, then for 50 to 80 we have another increasing linear equation
The sketch can be seen below.
