The expression we have is:

And we need to evaluate this expression when the value of y is:

Step 1. Substitute y=2 into every "y" that the expression has:

And now we can start solving the operations step by step.
Step 2. Solve the terms that have an exponent.
Since

And

The expression is now as follows:

Step 3. The next step is to solve multiplications and divisions.
We start with the first multiplication 7(8) which is 56:

Step 4. Solve the next multiplication 8(4) which is 32:

Step 5. Solve the division 24÷3 which results in 8:

Step 6. Finally, solve all of the additions and subtractions:

The result is 73, option D.
Answer:
D. 73
