Let x represent lower level tickets that cost $77
Let y represent upper level tickets that cost $99
Cost equation: 77x + 99y = 247,071
Tickets equation: x + y = 2615
Using the elimination method, multiply the second equation by -77:
77x + 99y = 247,071
-77x - 77y = -201,355
--> 22y = 45,716
--> y = 2,078
Now plug "y" into either equation and solve for "x". I chose the Tickets equation. x + y = 2615 → x = 2615 - y → x = 2615 - 2078 → x = 537
Answer: lower level = 537 tickets, upper level = 2078 tickets.

Answer:
distance driven < 300 miles.
Step-by-step explanation:
Plan A
She needs the car for 3 days.
1 day costs 60 dollars
3 days cost 60*3 = 180 So this is the maximum amount that she can spend
Plan B
She still needs the car for 3 days
1 day costs 20 dollars of the car does not move
3 days costs 3*20 = 60 dollars.
60 + 0.4m < 180 Subtract 60
0.4m < 180 - 60
0.4m < 120 Divide by 0.4
m < 120/ 0.4
m < 300
Answer
so she should drive less than 300 miles.
Answer:
Option C is correct.
The equation
represents the function.
Step-by-step explanation:
Using slope intercept form to find the equation of line :
For any two points
and
the equation of line is given by:
......[1] ;where m is the slope given by:

Consider any two points from table :
let (4, 2) and (0, 4) be any two points.
calculate slope:


Now, substitute in equation [1] we have:

Distributive property i.e, 

Add both sides 2 we get;

Simplify:

Since, y= f(x)

therefore, the equation
represents the function.
