Answer:
Step-by-step explanation:
Let k represent the price in dollars at which Nita will buy the keyboard.
We have been given Nita wants to buy a new keyboard for her computer. She will buy the keyboard when it is on sale for under $50.
This means that Nita will buy the computer, when its price (k) is less than $50. We know that sign < represents less than.
We can represent our given information in an inequality as:
Therefore, our required inequality would be .
The required function of the situation is f(x) = 2670x.
Step-by-step explanation:
Given,
Population is = 3000
Evert year it is decreased by 11%.
To find the function of the given situation.
Formula
If the original population is a and is decreased by b% the population after 1 year will be a×
After x year the population will be = a××x =
Now,
Let after x years the population will be,
f(x) = 3000x×
= 2670x
Hence,
The required function of the situation is f(x) = 2670x.
