valkas [14]

The statement that correctly calculates the average price of Will's books is

B. ($32 + $45 + $39) ÷ 3

This is because the average or mean, is found by adding all of the numbers together and then dividing the sum by the amount of numbers you added together (in this case 3.)

with that template in mind, let's see

$\bf \begin{array}{llll}
y=&-4sin(&\frac{2\pi }{3}x)\\
&A&B
\end{array}\qquad period\implies \cfrac{2\pi }{B}\implies \cfrac{2\pi }{\frac{2\pi }{3}}\implies \cfrac{\frac{2\pi }{1}}{\frac{2\pi }{3}}
\\\\\\
\cfrac{2\pi }{1}\cdot \cfrac{3}{2\pi }\implies 3$
