Answer: The required ratio of people to T-shirts sold is 5 : 1.
Step-by-step explanation: Given that one T-shirt is sold for every 5 people who attend a concert.
We are to find the ratio of people to T-shirts sold.
Let 1x represents the number of total T-shirts sold and 5x be the number of people that attended the concert.
Therefore, the ratio of people to T-shirts sold is given by
Thus, the required ratio of people to T-shirts sold is 5 : 1.

Answer:
Function for given situation is :
Value of computer after 4 years = $720.3.
Step-by-step explanation:
Given that the value of a $3000 computer decreases about 30% each year. Now we need to write a function for the computers value V(t). then we need to find about how much will the computer be worth in 4 years.
It clearly says that value decreases so that means function represents decay.
For decay we use formula:
where P=initial value = $3000,
r= rate of decrease =30% = 0.30
t= number of years
A=V(t) = future value
so the required function is
or
Now plug t=4 years to get the value of computer after 4 years.
Hence final answer is $720.3.
