Answer:
The answer is D, 43 [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
If the pile gets bigger by 8 [tex]\frac{7}{12}[/tex] each week, and you want to find out how big the pile is after 3 weeks, then you have to multiply 8 [tex]\frac{7}{12\\}[/tex] by 3 to find out how much the pile increased by.
8 [tex]\frac{7}{12\\}[/tex] × 3 = 25 [tex]\frac{3}{4}[/tex]
Now, you need to add this to your initial value to get the answer.
25 [tex]\frac{3}{4}[/tex] + 17 [tex]\frac{3}{4}[/tex] = 42 [tex]\frac{6}{4}[/tex]
Now simplify.
43 [tex]\frac{1}{2}[/tex]
