4 A skating rink charges $4 for ice skate rental and a
fee of $3 for each hour of skating. Kelsey paid a total
of $10 to rent skates and to skate for n hours. What
is the value of n ?

What is the value of n

N=2 hours

Step-by-step explanation:

She spent a total of 10 dollars.

Ice skate rental costs 4$

The fee per hour for skating is 3$ per hour

So minus 10$ by 4$, which is 6$

So now here at six and each fee per hour cost 3$, so therefore she skated for N= 2 hours.

the clues that signal the reader should change tone are the punctuation marks, the grammatical signs. for example, the quotation marks at the beginning of something someone else said literally or the exclamation marks.

the tone of the first line of dialogue until "gettysburg" is a kind tone, a tone of advise. the narrator is trying to the other person in doing something he or she obviously is finding hard to do by giving a piece of advise and bringing up a memory of a successful similar case.

the clue that the reader understand how to read the word "bang" is the exclamation mark. it gives the word a surprise tone, a strong accent.

the best tone for reading the word "bang" is an exciting tone, a surprise one, even a loud one.

the words that should be read with a formal tone are the ones that give factual information. the sentence: mister lincoln couldn't think of anything to say at the gettysburg" gives information about an event and it needs to be read formally, also, when the narrator wants to transmit calmness, a formal and slow tone is needed, because people also transmit messages with the vibrations of our voices and tones.
