Step-by-step explanation:
y = -16/25x + 48
Answer: $56.25
Step-by-step explanation:
Money: $1000
Interest: 7.5% or ![\frac{7.5}{100} =0.075](https://tex.z-dn.net/?f=%5Cfrac%7B7.5%7D%7B100%7D%20%3D0.075)
There are two steps you can use to find this.
First
---------------------------------------------------------------------------------------------
To find the annual interest multiply by the rate.
![(1000)(0.075)\\=75](https://tex.z-dn.net/?f=%281000%29%280.075%29%5C%5C%3D75)
We can now find how much that is per month;
per month, to find how much that is in 9 months, multiply by 9
![6.25*9=56.25](https://tex.z-dn.net/?f=6.25%2A9%3D56.25)
----------------------------------------------------------------------------------------------
Second
You know 12 months is 1 year, you divide the amount of months that we're trying to calculate the interest of, by the amount of years in months; in this case, 12.
![\frac{9}{12}=0.75](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B12%7D%3D0.75)
Multiply that by the interest and the total amount.
![(0.75)(0.075)(1000)\\= 56.25](https://tex.z-dn.net/?f=%280.75%29%280.075%29%281000%29%5C%5C%3D%2056.25)
