Mr. anderson is taking a group of junior high school students (7th and 8th graders) on a field trip to a local observatory. the cost for 7th graders is $6 and the cost for 8th graders is $6.50. in the equation c = 6x + 6.5y, what does the variable c represent?

Variable C represents the total cost for both 7th and 8th grade students.

Step-by-step explanation:

Variable C represents the total cost for both 7th and 8th grade students.

The variable "x" represents the number of 7th grade students who go on the field trip, that is the number of times the total cost increases due to the cost of 7th grade students, which is $6 for each.

The variable "y" represents the number of 8th grade students who go on the field trip, that is the number of times the total cost increases due to the cost of 8th grade students, which is $6.50 for each.

Hope this helps!

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

3 qrs + 3/2 xy hope this : /
