Mandy had 22 correct her grade was 80% how many questions on the test?

0.8x = 22

823

To determine the number of questions on the test, we need to use the given information about Mandy's correct answers and the percentage of her grade.

Let's follow these steps to find the answer:

Step 1: Set up a proportion using the information given:
Correct answers / Total questions = Grade percentage / 100%
22 / Total questions = 80 / 100

Step 2: Simplify the proportion:
22 / Total questions = 8 / 10

Step 3: Cross-multiply to isolate the variable:
8(Total questions) = 22 * 10

Step 4: Solve for (Total questions):
8(Total questions) = 220
Total questions = 220 / 8
Total questions = 27.5

Since we can't have a decimal number of questions, we need to round up to the nearest whole number because a test cannot have a fractional question. Therefore, the test had a total of 28 questions.
