Games unlimited buys video games for $10. the store increases the price 300%. what is the price of the video game?

To solve this problem, identify the starting payment for video games that is given in the question. This is $10.

Since the company decides to increase the price by 300%, you have to multiply to get the new price.
Start by finding 100% on $10.
Since 100% of $10 is all that is there, that is another $10.

So now that you know a baseline for the increase in price, multiply that base by three to find the increase in price.
10 x 3 = 30

So, the company adds $30 to the price.
A simple addition problem gives you the new final price:
10 + 30 = 40

So, video games are now bought for $40 rather than $10.

I hope this helps! :)
