C. 3h

D. H/3

9514 1404 393

  C. 3h

Step-by-step 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.

step-by-step explanation:

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
