My work also shows the means and the medians to compare.
The equation would be C= 50p. For 15 people, it would cost $750.
Answer:
3x+4=40
Step-by-step explanation:
Lets take "x" as the number of students who went on the trip last year
It says "3 times" the number of seventh grade students that went on the trip last year so we know that x will be multiplied by 3
It also says 4 more than so we know that 3x+4 is gonna be part of the equation
If 40 students went on this years trip then 3x+4=40
Answer:
$7500
Step-by-step explanation:
Given
![I = 525](https://tex.z-dn.net/?f=I%20%3D%20525)
![R = 3.5\%](https://tex.z-dn.net/?f=R%20%3D%203.5%5C%25)
![T =2](https://tex.z-dn.net/?f=T%20%3D2)
Required
The Principal
This is calculated using:
![I =PRT](https://tex.z-dn.net/?f=I%20%3DPRT)
Make P the subject
![P = \frac{I}{RT}](https://tex.z-dn.net/?f=P%20%3D%20%5Cfrac%7BI%7D%7BRT%7D)
So, we have:
![P = \frac{525}{3.5\% * 2}](https://tex.z-dn.net/?f=P%20%3D%20%5Cfrac%7B525%7D%7B3.5%5C%25%20%2A%202%7D)
![P = \frac{525}{7.0\%}](https://tex.z-dn.net/?f=P%20%3D%20%5Cfrac%7B525%7D%7B7.0%5C%25%7D)
![P = 7500](https://tex.z-dn.net/?f=P%20%3D%207500)
