Mark is playing a trivia game. On his first turn, he lost 100 points. On his second turn, he lost 55 points. On his third turn, he lost 65 points. Enter a sum that models the change to Mark's score after his first three turns. HELPP WORTH 15 POINTSS

It’s easier to take this question step-by-step.

Mark starts with 0 points.

Since he loses 100 points on his first turn, we can subtract.

0 - 100 = -100

From there, he loses another 55 points, meaning we subtract that from his first-turn total.

-100 - 55 = -155

On his third turn, he loses another 65 points, so we subtract from his second-turn total.

-155 - 65 = -220

Therefore, Mark’s total points at the end of three turns is -220.

Hopefully this helps! :)
