Answer:
One student costs $3.75
Step-by-step explanation:
Unit rate is how much it is for 1 item. In this case, we want to know the cost for 1 student.
$30/8 students ... if it is $30/8 students, you can divide by 8 to find out how much it is for one student.
$30/8 = $3.75
50 students on the fist day and you multiply that by .20 to find how much is 20 percent of 50. You take that number which is 10 and subtract it from 50 so 50-10=40 which is how many showed up the second day
Just Math
50*0.2=10
50-10=40 students
Move 6x to the right side: 2y=12-6x
Divide both sides by 2: y=6-3x
m is the slope which in this case is -3
To see a graph plug y=6-3x into the website wolfram alpha!
Hope this helps!!
It would be the first one
