Answer:

C. 3h

Explanation:

In algebra, multiplication by a number is indicated by placing the number next to the variable, with or without a multiplication symbol.

3×h = 3·h = 3h

In plain text, the asterisk (*) is sometimes used as a multiplication symbol. Some folks will use a period (decimal point) as a multiplication symbol, but that tends to be confusing.

"Triple" means "three times", so the number of hair ties Michaela's sister has is ...

3 times h = 3h

_____

Additional comment

The caret (^), as in h^3, is used to signify repeated multiplication. The term h^3 means h×h×h. This is not the same as h+h+h = 3h.

The slash is used to signify division.

3/h means 3÷h.

h/3 means h÷3.

If Michaela's sister had h/3 hair ties, she would have one-third the number Michaela has. That is not the same as 3 times the number Michaela has.
