Step-by-step explanation:
Percentages
The x percent of a number N is calculated as:
[tex]\displaystyle P=\frac{x}{100}*N[/tex]
If the value of P is known, then:
[tex]\displaystyle N=\frac{100}{x}*P[/tex]
We know the store sold P=550 video games during the month of December and it corresponds to the x=12% of its yearly games sales (N).
Let's calculate N:
[tex]\displaystyle N=\frac{100}{12.5}*550[/tex]
N = 4,400
The store sold 4,400 video games all year.
