3-58.

Dr. Sanchez asked her class to simplify the expression $x + 0.6x$, but some students disagree on how to simplify it. Terry says that $x + 0.6x = 1.6x$, but Jo says that $x + 0.6x = 0.7x$. Who is correct? Justify your conclusion.

Terry is correct.

(1) $x + 0.6x = 1.6x$

Be sure to explain why.
