Answer:
160,000
Step-by-step explanation:
Estimations like this usually involve rounding to easy numbers to multiply. You could do this in a number of ways depending on your ability to keep track of factors in your head, but the easiest way (and what I assume your teacher is looking for) is to round to the nearest, largest-power-of-ten, which in this case is the hundreds. 786 is closest to 800, and 217 is closest to 200, and 200*800 is 160,000. No calculator required is the key. You can also be slightly more sure that this is <em>reasonable</em> because you rounded up for one and down for the other, approximately by the same amount, too.

Answer:
c(x) = ($12) / x
Step-by-step explanation:
The general formula for inverse proportion is y = k/x.
In this specific problem, y represents the cost per person, k the dailyl cost ($12), and x the number of perople riding.
Then
c(x) = cost per person as a function of the number of people riding
= ($12) / x
Note that if only one person rides, that person pays $12/1, or $12; if two people, $12/2, or $6 per person, and so on.
Cost depends on the class size , so
cost is the dependent variable and class size is the independent.
Hello!
I believe the answer is dividend.
Look at it like this..
10 / 5 = 2
^ ^
dividend divisor ^ quotient.
Hope this helps! ☺♥
