Answer:
100%
Step-by-step explanation:
there's there's a total then if you got example 5/5 or 95/95 you would get 100%
A cause u gotta buy a new one instead of used or borrowing it
Answer:
A. He has $22 because he spends $2 on snacks each day.
B. He spends $2 a day, in the table we can see it decreases by $2 each day, so he spends $2 every day.
C. Yes because the cost evenly decreases by $2, therefore it is a linear relationship.
D. ?
E. X ÷ Y = Z
X being the money, $22
Y being the days, 6
Z being the leftover money, $8
Given:
The value of car before two years = £10000
The value of the car decreases by 5% each year.
To find:
The present value of the car.
Solution:
The exponential decay model for present value is
![y=a\left(1-\dfrac{r}{100}\right)^t](https://tex.z-dn.net/?f=y%3Da%5Cleft%281-%5Cdfrac%7Br%7D%7B100%7D%5Cright%29%5Et)
Where, a is the initial value, r is the rate of decay and t is time in years.
Putting P=10000, r=5 and t 2, we get
![y=10000\left(1-\dfrac{5}{100}\right)^2](https://tex.z-dn.net/?f=y%3D10000%5Cleft%281-%5Cdfrac%7B5%7D%7B100%7D%5Cright%29%5E2)
![y=10000\left(1-0.05\right)^2](https://tex.z-dn.net/?f=y%3D10000%5Cleft%281-0.05%5Cright%29%5E2)
![y=10000\left(0.95\right)^2](https://tex.z-dn.net/?f=y%3D10000%5Cleft%280.95%5Cright%29%5E2)
On further simplification, we get
![y=10000(0.95)(0.95)](https://tex.z-dn.net/?f=y%3D10000%280.95%29%280.95%29)
![y=9025](https://tex.z-dn.net/?f=y%3D9025)
Therefore, the present value of the car is £9025.
