4) Stacy is thinking of a number, which she calls \( n \). She triples it and then adds 10.
(1)) Write an expression to represent Stacy's final number.
\[
3 n+10
\]
(1) What is Stacy's final number in her starting number is 12?
\[
3 n+10=3(?)+10
\]
\(= 46\)
Step 1 :\(3n+10 = 3(12) + 10\)
Step 2 :\(= 36 + 10 \)
Step 3 :\(= 46\)
