After earning 300 points on a game show, katie got to compete in the bonus round. by the end of the bonus round, she had a total of 800 points. what was katie's score for the bonus round?

500

Step-by-step explanation:

First we make an equation to find the score for the bonus round. x is the score for the bonus round .

300 + x = 800

Next we subtract 300 from both sides of the equation

300 - 300 + x = 800 - 300

Which get us

0 + x = 500

x = 500

Her score in the bonus round is 500
