I answered a 40-item examination. I get five points for every correct answer and lose two points for every wrong answer. What is my total score if I correctly answered 75% of the items?

"75% correct
25% wrong

0.75 × 40 = 30
0.25 × 40 = 10

30 correct answers x 5 points = 150

10 wrong x 2 = 20 points deduction

Total score = 150 - 20
= 130"
