Aclass is going on a field trip to see a movie. each ticket is $10.00. the number of students, n, who will receive a $10.00 ticket is proportional to the total cost, c, of all the tickets. which equation could be used to find the total cost of all the tickets?

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
