Answer this correctly is the answer yes or no

there are 3 teaspoons in one tablespoon then 4 bottles have a combined total of 4 tablespoons.  

if you have 3 teaspoons in one bottle and you have 4 bottles that will make 12 teaspoons,  for every 3 teaspoons it is equal to one tablespoon.  so you divide 3 into 12 which will make  4 tablespoons.

your is no

answer:

Step-by-step explanation:

40x^2+800x+12000

= x^2+20x+300

if y = x^2+20x+300

then the max is calculated by finding the value of first derivitive, that is:

y' = 2x+20 = 2(x+10)

y' = 2(x+10) = 0 then x = 10

that is the price of the ticket is $2.00

Verification:

At the price of $1.90, (total riders 8400) the total revenue will be  $15,960 and

 ...              

 $2.00, (total riders 8000)   ...                              

$16,000 and  

<- max revenue

 ...                

$2.10, (total riders 7600)  ...                              

$15,960

answer: $2.00 per ticket will maximize the revenue.
