Answer:
15. 6647.61
16. 553
Step-by-step explanation:
Let L represent lower level tickets and U upper level.
Starter equations:
L + U = 2368
78L + 59U = 157800
Solve simultaneous equations:
59L + 59U = 139712
so 19L = 18088
L = 952
U = 2368 - 952 = 1416
952 lower level tickets and 1416 upper level tickets were sold.
No no. no no n on o n in o n o b o n
you turn 1 and 1 over 5 into 6 over 5. then divide.
12 divided by 6 over 5 equals 10
