Can u pls help me with this question

The answer is D, 43  

Step-by-step explanation:

If the pile gets bigger by 8 each week, and you want to find out how big the pile is after 3 weeks, then you have to multiply 8 by 3 to find out how much the pile increased by.

8 × 3 = 25

Now, you need to add this to your initial value to get the answer.

25 + 17 = 42

Now simplify.

43
