Explanation:

Answer 2

X_sat =
`\left[\begin{array}{ccc}36\\150\\126\end{array}\right]`

Explanation:

Let,

x = number of cakes produced

y = number of muffins produced

z = number of pastries produced

Friday

x = 12

y = 50

z = 42

X =production

X_friday =
`\left[\begin{array}{ccc}x\\y\\z\end{array}\right]` =
`\left[\begin{array}{ccc}12\\50\\42\end{array}\right]`

His goal for Saturday is to bake 3 times as many of each item

X_sat = 3*X_friday

X_sat = 3*
`\left[\begin{array}{ccc}x\\y\\z\end{array}\right]`

X_sat =
`\left[\begin{array}{ccc}36\\150\\126\end{array}\right]`
