44% more right than wrong answers.

Explanation:

Tina scored 18 out of 25 correct.

As a percent:
18/25 xx100% = 72% of the answers correct.

She must have had $25 - 18 = 7$ answers wrong.
As a percent:
7/25 xx100% = 28% of the answers wrong.

The difference in percent between the right and wrong answers is:

72%-28% = 44%#
