Answer:

a) Matrix B = $\left[\begin{array}{c}5\\7\\9\end{array}\right]$

b) Matrix AB = $\left[\begin{array}{c}2525\\3620\\2845\\3705\end{array}\right]$

c) $12,695

Step-by-step explanation:

Matrix A = $\left[\begin{array}{ccc}225&110&70\\95&160&225\\280&65&110\\0&240&225\end{array}\right]$

a) Matrix B = $\left[\begin{array}{c}5\\7\\9\end{array}\right]$

Gross Receipt = AB

$\left[\begin{array}{ccc}225&110&70\\95&160&225\\280&65&110\\0&240&225\end{array}\right]$ . $\left[\begin{array}{c}5\\7\\9\end{array}\right]$ = $\left[\begin{array}{c}2525\\3620\\2845\\3705\end{array}\right]$

c) Total revenue is the sum of receipts from 4 cinemas given in part b

Hence,

Total revenue = $2525 + $3620 + $2845 + $3705 = $12,695

Answer:

Step-by-step explanation:

8 gallons of regular gas with 10% and 2 gallons with 85%

8 x 10 =80%

2 x 85 =170%

170+80=250%

10 gallons each with 100%, so 10 x 100 =1000%

250% of 1000% = 1/4 or 25% ethanol

Hope this helps!
