maria’s math test
correct answers 17
incorrect answers 3
what percentage of questions did maria answer correctly?
75%
80%
85%
90%

Explanation:

Step1: Find total questions

To find the total number of questions, we add the number of correct answers and incorrect answers. So, total questions = correct answers + incorrect answers = \(17 + 3 = 20\).

Step2: Calculate percentage of correct answers

The formula for percentage of correct answers is \(\frac{\text{Correct Answers}}{\text{Total Questions}} \times 100\%\). Substituting the values, we get \(\frac{17}{20} \times 100\% = 0.85\times100\% = 85\%\)? Wait, no, wait, 17 divided by 20: 17/20 = 0.85? Wait, no, 17 + 3 is 20. 17/20 = 0.85? Wait, 17 divided by 20: 200.85 = 17. Wait, but the option with 85% is there. Wait, but the selected option in the image is 80%, but let's recalculate. Wait, 17 correct, 3 incorrect. Total questions: 17 + 3 = 20. Percentage correct: (17/20)100 = 85%. Wait, maybe I made a mistake? Wait, no, 17 divided by 20: 17 ÷ 20 = 0.85, times 100 is 85%. So the correct answer should be 85%. Wait, but the options are 75%, 80%, 85%, 90%. So 85% is an option. So let's check again.

Wait, maybe the table was misread? Let me check again. Correct Answers: 17, Incorrect: 3. Total: 20. 17/20 = 0.85 = 85%. So the correct percentage is 85%.

Answer:

C. 85% (assuming the options are labeled A:75%, B:80%, C:85%, D:90%)
