A store sold 550 video games during the month of December if thus made up 12.5% of its yearly video game sales about how many video games did the store sell a year

What we can do is find the fraction of 12.5 in 100% to solve for the answer:

100/12.5 = 8

We know that it's 8, which tells us that the store has to sell 550 games 8 times:

550 * 8 = 4400

The store sells 4400 games a year.
