Answer:
X_sat = [tex]\left[\begin{array}{ccc}36\\150\\126\end{array}\right][/tex]
Step-by-step 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 = [tex]\left[\begin{array}{ccc}x\\y\\z\end{array}\right][/tex] = [tex]\left[\begin{array}{ccc}12\\50\\42\end{array}\right][/tex]
His goal for Saturday is to bake 3 times as many of each item
X_sat = 3*X_friday
X_sat = 3* [tex]\left[\begin{array}{ccc}x\\y\\z\end{array}\right][/tex]
X_sat = [tex]\left[\begin{array}{ccc}36\\150\\126\end{array}\right][/tex]
