Given:

Jack's scores in five successive rounds were 25,-5,-10, 15 and 10.

To find:

The total score at the end.​

Solution:

It is given that the scores in five successive rounds were 25,-5,-10, 15 and 10. So, the sum of the scores at the end is:


Sum=25+(-5)+(-10)+15+10


Sum=(25+15+10)+(-5-10)


Sum=50+(-15)


Sum=50-15


Sum=35

Therefore, the total score at the end. is 35.
