Explanation: it’s a histogram, which is similar to a bar graph, but its data points lie within ranges with values.
Initial price of car = $x
After one year the price of car = $0.88x
to find the change in price we subtract the price after one year from initial price.
It means change in price = (x-0.88x)= 0.12x
By this we can easily see that , price dropped by 0.12
Or we can say that price dropped by 12%
So option C is the correct answer
C) 12% decrease
A relative frequency table is a graph that depicts the popularity or pattern of a certain piece of data based on the population sampled. The value of x will be 85.
<h3>What is a relative frequency table?</h3>
A relative frequency table is a graph that depicts the popularity or pattern of a certain piece of data based on the population sampled.
When we examine the relative frequency, we examine the number of times a certain event happens in comparison to the overall number of events.
We have the following equation for the adult column;


Hence the value of x will be 85.
