Question

A store sold 550 video games during the month of December. If this made up 12.5% of its yearly video games scales, about how many video games did the store sell all year?

Answer 1

Answer:

The store sold 4,400 video games all year.

Step-by-step explanation:

Percentages

The x percent of a number N is calculated as:

$\displaystyle P=\frac{x}{100}*N$

If the value of P is known, then:

$\displaystyle N=\frac{100}{x}*P$

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:

$\displaystyle N=\frac{100}{12.5}*550$

N = 4,400

The store sold 4,400 video games all year.
