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.
D and a because they both dont change the answer and b
Answer:
B = 6√10
Step-by-step explanation:

Answer:
An equation
Step-by-step explanation:
this can be solved too
4g + 7e + 4 + 9 + (-4e) + 11 = 5g + 3e + 15
combine like terms
4g + 3e + 24 = 5g + 3e + 15
3e + 24 = g + 3e + 15
24 = g + 15
9 = g
and
0 = e or *no solution* since e cancels itself out.
