10/25 = 2/5 Because you divide both sides by 5
Given:
Cost of 1 digital song = $1.05
Cost of 2 digital song = $2.10
Cost of 5 digital song = $5.25
To find:
The equation and the cost of 25 downloaded digital songs.
Solution:
Let us take two points (1, 1.05) and (2, 2.10).
Here 
Slope:
m = 1.05
Using point-slope formula:
Add 1.05 on both sides, we get
Here x is the independent variable and c is the dependent variable.
So that substitute x = n and y = c.
The equation is c = 1.05 n.
Substitute n = 25 in the equation.
The cost of 25 songs is $26.25.
Answer: y=1/4 x - 7
Found the equation using slope-intercept form
The difference between the median of the golf pro box and tennis pro box is 20.
<h3>
What is Median?</h3>
The median is the middle value of an entire data set. If the number of data points(observations) in the set is odd then the middle value is the median but, for an even number of observations, the median is calculated by finding the means for the two middle data points.
As we know that the vertical line in the box plot is the median. Therefore, the median of the Golf pro shop is 40, while the median of the tennis pro shop is 20.
The difference between the median of the golf pro box and tennis pro box
= 40 - 20
= 20
Hence, the difference between the median of the golf pro box and tennis pro box is 20.
