748 student tickets were sold.
Step-by-step explanation:
Given, 
Number of tickets sold = 1360 
Revenue generated = $13328
Cost of each student ticket = $8
Cost of each non student ticket = $12 
Let, 
x be the number of student tickets sold 
y be the number of non student tickets sold
According to given statement;
x+y=1360        Eqn 1
8x+12y=13328    Eqn 2
Multiplying Eqn 1 by 12

Subtracting Eqn 2 from Eqn 3

Dividing both sides by 4

748 student tickets were sold.

Answer:  The answer is 284. 
Step-by-step explanation: 
The area of the garden is an annulus whose,  
Outer diameter = 18 ft  
Inner diameter = 18 ft - 2*3ft = 12 ft
 Therefore,  
Outer radius = 18/2 = 9 ft  
Inner radius = 12/2 = 6 ft  
  Area of garden = Area of annulus  
  Area of garden = π*(9 ft)2 - π * (6 ft)2
  Area of garden = 142  
  Given:  
2 flowers are planted per square foot.  
  Therefore for 142 ft2,  
Number of flowers required = 2*142 = 284  
  The answer is 284.
