Answer:
• 800 pavilion seats
• 800 lawn seats
Step-by-step explanation:
Let p represent the number of pavilion seats sold. Then 1600-p is the number of lawn seats sold. Total revenue is ...
25p +20(1600 -p) = 36000
5p + 32000 = 36000
5p = 4000
p = 800 . . . . . . . . . . number of pavilion seats sold
1600-p = 800 . . . . . number of lawn seats sold
_____
You can work these problems in your head. Consider that all seats were sold at the lower price. Then revenue would be 1600·20 = 32000. It was 36000 -32000 = 4000 more than that. The difference in ticket price is 25 -20 = 5 dollars, so there must have been 4000/5 = 800 higher-priced tickets sold. (Compare this working to the math above. You will find it substantially similar.)
Answer:
I beleive the answer is $9000
Step-by-step explanation: What is 18% of 50000?
Y is 18% of 50000
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 18% * 50000
Converting percent to decimal:
p = 18%/100 = 0.18
Y = 0.18 * 50000
Y = 9000
