Marks awarded for every right answer #=> +2#
No. of right answers #=> 2#

Marks deducted for every wrong answer #=> -1#
No. of wrong answers#=> 5#

Total score #=> " (no. of right answers)"("marks awarded") + " (no. of wrong answers)"("marks deducted")#

#=> 2xx2 + 5 xx-1#

#=> 4-5 = -1#

Her total score is #-1#.

~Hope this helps! :)
