Answer:
14/27 feet
Step-by-step explanation:
2 1/3 feet : 4 1/2 feet
= 7/3 : 9/2
= 7/3 ÷ 9/2
= 7/3 × 2/9

= 14/27 feet
2 1/3 feet : 4 1/2 feet = 14/27 feet
1) a = tickets in advance goal = 2000
d =tickets at door
6a +8d = 2000
6(142)+8d =2000
852+8d=2000
8d=2000-852
8d=1148
d=1148/8
d=143.5
round up d=144 need to sell 144 tickets at door
