Well, first you want to find what percent 7 is of 183. to do this, divide 7 by 183.
7 / 183 = 0.03825136612.. which gives us a decimal, which we can round to 0.038. next, we can multiply by 100 to get the percent.
0.038 x 100 = 3.83%
That's the percentage of days Holly was NOT in attendance, to find how many she was, subtract the total (100) minus what she was out for.
100 - 3.83 = 96.17, which we can round to 96% making A your answer.
I hope this was helpful have a great rest of your day!
Edit: made a small grammatical change :)
