The temperature of the room is 74F
<em></em>
Step-by-step explanation:
Given

Solving (a): The temperature at the start.
To do this, we set: 
So, we have:




<em>Hence, the temperature at the start is 35F</em>
<em></em>
Solving (b): The room temperature
We have:

To get the temperature of the room, we simply remove the exponential function.
So, we have:

<em>Hence, the temperature of the room is 74F</em>
Answer:
He purchases a total of 6 tickets: $16 for the first and $5 each for 5 more tickets.
Step-by-step explanation:
Here we need an equation with a constant term and a variable term:
$71 total = $16 + ($11/ticket)*(t tickets)
Subtracting $16 from both sides, we get
$55 + ($11/ticket)*(t tickets)
Dividing both sides by ($11/ticket)
results in
$55
-------------- = 5 tickets (beyond the first one)
$11/ticket
