Dana rasied the score on a video game from 300 points to 390 points. By what percentage did Dana raise the score?

30%

Step-by-step explanation:

First find the difference between the old score and the new:

= 390 - 300

= 90 points

To find the percentage increase, divide the difference by the original score:

= 90 / 300

= 30%

only 10/60 isn't equivalent
