Ok, let us use "C" as our variable that will equal the normal price.
(C - $.75) 7 = $2.80
Divide both sides of equation by 7
C - $.75 = $2.80 / 7 Add $.75 to both sides of equation
C = $.40 + $.75
C = $1.15
The number of songs that Deante' would have downloaded during month 9 is 58 songs.
<h3>What is a regression line?</h3>
A regression line is a statistical line that best describes the behavior of a data set and such, it is a line that best fits a set of data.
By using Microsoft excel to plot the data on a scatter plot, we can logically deduce that line of best fit for the songs downloaded is given by:
y = 2.03x + 39.7
Thus, the number of songs that Deante' would have downloaded during month 9 is:
y = 2.03(9) + 39.7
y = 18.27 + 39.7
y = 57.97 ≈ 58 songs.
