$3-\dfrac{1}{2}\left(\log6+\log3-3\log2\right)=\\
\log10^3-\dfrac{1}{2}\left(\log\left(6\cdot3\right)-\log2^3\right)=\\
\log1000-\dfrac{1}{2}\left(\log18-\log8\right)=\\
\log1000-\dfrac{1}{2}\left(\log\dfrac{18}{8}\right)=\\
\log1000-\dfrac{1}{2}\left(\log\dfrac{9}{4}\right)=\\
\log1000-\log\left(\dfrac{9}{4}\right)^{\dfrac{1}{2}}=\\
\log1000-\log\sqrt{\dfrac{9}{4}}=\\
\log1000-\log\dfrac{3}{2}=\\
\log\dfrac{1000}{\frac{3}{2}}=\\
\log\left(1000\cdot\dfrac{2}{3}\right)=\\
\log\dfrac{2000}{3}$

nataly862011 [7]

Course Cost = $12 + $12 * 10
Course Cost = $24 * 10
Course Cost = $240

Equipment = $275 +$60 + $75 +$32.50 +$35
Equipment = $477.50 * .08
Equipment = $477.50 + $38.20
Equipment = $515.70

Course Cost + Equipment = Total Cost
$240 + $515.70 = $755.70
Total Cost = $755.70
