Answer:

20/4 would be on the printed 5 point and 13/4 would be 3 1/4 so it would be on the line one to the left of 3.

Step-by-step explanation:

<h3>It is like division 20/4 = 20 ÷ 4 which would be 5. Then for 13/4 you know that 12/4 = 3, so that would leave you with 1/4. So 13/4=3 and 1/4</h3>

The cost per student of a ski trip varies inversely as the number of students who attend. It will cost each student $250 if 24 s
mars1129 [50]

ANSWER

30 students

EXPLANATION

The cost per student varies inversely as the number of students.

Inverse proportion is written as:

\begin{gathered} y\propto\frac{1}{x} \\ y=\frac{k}{x} \\ \text{where k = constant of proportionality} \end{gathered}

Let the cost per student be y.

Let the number of students be x.

It will cost each student $250 if 24 students attend. This means that:

\begin{gathered} 250=\frac{k}{24} \\ \Rightarrow k=250\cdot24 \\ k=6000 \end{gathered}

If the cost is down to $200, it means that y is now $200.

That is:

\begin{gathered} 200=\frac{6000}{x} \\ \Rightarrow x=\frac{6000}{200} \\ x=30\text{ students} \end{gathered}

Therefore, 30 students could attend.
