Answer:
a = 195 ; c = 615
Step-by-step explanation:
So, you want to start by forming your equations...
I will use 'c' for children and 'a' for adults for my variables
3a + 30 = c
(this is because of the info that 30 more tickets than 3 times the amount of children's were sold than adult)
then for equation 2:
3c + 5a = 2820
(this is because of the prices of the tickets and the total money raised)
Then, plug in the equation for c
Your equation should look like:
3(3a + 30) + 5a = 2820
You get:
(9a +90) + 5a = 2820
Then:
14a = 2730
So:
a = 195 adult tickets sold
Plug in a, to find c:
3 (195) + 30 = c
585 + 30 = c
c = 615 children tickets sold
Answer with Step-by-step explanation:
We are given that
Height of ball after t seconds is given by
a.Substitute the value of t=1
b.Differentiate w.r.t x
Again differentiate w.r.t t
Hence, the height is maximum at t=2.5 s
Maximum height of the baseball=27 ft
Number of general admission tickets sold is 75
<u>Step-by-step explanation:</u>
Step 1:
Let the number of general admission tickets be x, then the number of student ID tickets = 200 - x. Total cost of tickets sold = $625
Cost of general admission tickets = 5x
Cost of student ID tickets = 2(200 - x) = 400 - 2x
Total cost of tickets = 5x + 400 - 2x = 625
⇒ 3x + 400 = 625
⇒ 3x = 225
⇒ x = 75
