Madeline sold 200 tickets for a charter flight to Dallas. Some paid $200 for their tickets and some paid $250. Madeline's revenue for the flight was $44,000. Below is Madeline's work in determining how many of each ticket was sold.
x = number of $200 tickets
y = number of $250 tickets
200x + 250y = 44,000 Complete each of the
x + y = 200
3 activities for this
Task.
200(200 - y) + 250y = 44,000
40,000 -y + 250y = 44,000
40,000 + 249y = 44,000
249y = 4,000
y = 16.1

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

you meant circumference well the answer is:

17.27876 miles

area is 23.7583

the radius is 2.75 miles

hope this hmu if needed.
