Rihanna must put a five dollar deposit down to buy a necklace. If P where presents the full price of the necklace which expressi
natta225 [31]

Answer:

<em>The expression is </em><em>P - 5</em>

Step-by-step explanation:

Rihanna already made a deposit of $5 to buy the necklace (given)

Full price of necklace = P

Let m = how much Rihanna has left to pay

Full price of necklace = amount paid + amount left to pay

= 5 + m

So we equate the two full necklace prices

5 + m = P

m = P - 5

Therefore, the amount Rihanna owes before tax = P - 5

I hope I am getting this right. 25 is increased to 100 is the answer 300%?
Mandarinka [93]
Whoa just a second there.

What is the question ?

Is the question "Find the percent of increase ?"

In that case, the answer is 300% .
Here's why:

The amount of increase is 75.

The amount of increase as a fraction of
the original amount is
                                       75 / 25  =  3.00 .

To change any number to a percent,
move the decimal point 2 places that way ===> .

                                           3.00  =    300% .
______________________________

The question could have been different.

It could have been "What is the amount of the increase ?"
That's 75.

It could have been "How many times larger is 100 than 25 ?"
100 is 4 times as large as 25, and 3 times larger.

It could have been "How many times has 25 been increased ?"
This is a terrible question ... there are a lot of those in schools.
The answer could be "25 was only increased once, by 75."
The answer could be "25 was increased to 4 times its size."
The answer could be "25 was increased by 3 times its size."

Jessica wants to give a 20% tip to a taxi driver. If the fare is $23.78, what amount did she tip the driver?
dedylja [7]
You should mulitply. $23.78 * 0.20 = 4.756

 Then you add. 4.756 to $23.78 = $28.536

Now you round $28.536 to the hundredths so that you can pay it with coins. 

The anwser is  $4.76 and the total amount for the taxi ride would be $28.54
