Marta takes a three part physical endurance test. in part 1 she loses 18 points. in part 2 she gains 22 points, and in part 3 she gains 4 points. what is marta’s score on the endurance test?

So, assume she starts at 0. Then, subtract 18, sense she lost 18 points.

She now has -18 points. Part 2, she gained 22, so its -18 + 22, which is 4.

She now has 4 points. Part 3, she gained 4 points, so its 4 + 4, which is 8.

 Marta's score on the endurance test is 8.

Hope this helps!!!
