Hey there! I'm happy to help!
First off, we see that 23 and 9 are added. This means we need to look for an answer option that says the sum of 23 and 9.
We see that answers C and D mention the sum of 23 and 9. Answer C says half the sum of 23 and 9 minus 89. There is no -89 in the problem, so this is incorrect.
Therefore, the answer is D. triple sum of 23 and 9 subtracted from 89.
Have a wonderful day! :D
