Answer:</h3>
- B. f(x) = 3,000(0.85)^x
- $1566.02
<h3>
Step-by-step explanation:</h3>
Part A
At the end of the year, the value of the computer system is ...
... (beginning value) - 15% · (beginning value) = (beginning value) · (1 - 0.15)
... = 0.85 · (beginning value)
Since the same is true for the next year and the next, the multiplier after x years will be 0.85^x. Then the value after x years is ...
... f(x) = (beginning value) · 0.85^x
The beginning value is given as $3000, so this is ...
... f(x) = 3000·0.85^x
____
Part B
For x=4, this is ...
... f(4) = 3000·0.85^4 = 3000·0.52200625 ≈ 1566.02
The value after 4 years is $1566.02.
Length of the median would be: a+b / 2 = 19+38 / 2 = 57/2 = 28.5
<span>Please be more clear with what you want for your answer. </span>
4x+3x+1x=t, where x represents the number of people, and t represents the total cost.
So to solve it, it says Fitz and 3 friends so that’s four people, you’d substitute x for 4.
I hope this helps!
