Answer:40%.
Since the student got 60% correct, the remaining percentage would be the part they got incorrect.
I got 60% by translating 9/15 into a decimal and moving the decimal point to create a percentage.

Step-by-step explanation:
Total number is 40
Percentage asked is 75

= 30
Therefore the correct answer is 30
Please use " i " to denote "interest."
the formula for simple interest is i = p r t.
Here, i = $160.67 = $2000 (r) (8/12)
Solving for the interest rate, r = ($169.67)(12/8)/ $2000 = 0.127, or 12.7%
