Answer:
- 300 adult tickets
- 600 student tickets
Step-by-step explanation:
We can group tickets into a group that has 2 student tickets and 1 adult ticket for a price of 2($1.25) +2.25) = $4.75. The number of these groups sold is ...
$1425/4.75 = 300
300 adult tickets and 600 student tickets were sold.
The answer would be f'(x)=15. the constant 15 would be left alone and the derivative of x is just one giving you the 15 left over. -16 is not connected to a letter so the derivative of that would be 0.
