Answer:
The equation to determine the number of album sold last month is [tex]200+12x=644[/tex].
Floyd sold 37 albums last month.
Step-by-step explanation:
Given:
Base rate = $200
Additional on each album sold = $12
Amount earned last month = $644
We need to write and solve an equation to find the number of album sold last month.
Solution:
Let the number of album sold last month be 'x'.
So we can say that;
Amount earned last month is equal Base rate plus Additional on each album sold multiplied by number of album sold.
framing in equation form we get;
[tex]200+12x=644[/tex]
Hence The equation to determine the number of album sold last month is [tex]200+12x=644[/tex].
On Solving the above equation we get;
Subtracting both side by 200 we get;
[tex]200+12x-200=644-200\\\\12x=444[/tex]
Dividing both side by 12 we get;
[tex]\frac{12x}{12}=\frac{444}{12}\\\\x=37[/tex]
Hence Floyd sold 37 albums last month.
