Answer:
The interest earned is $421.2.
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:
In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
In this question:
![P = 2880, I = 0.045, t = 3 + \frac{1}{4} = 3.25](https://tex.z-dn.net/?f=P%20%3D%202880%2C%20I%20%3D%200.045%2C%20t%20%3D%203%20%2B%20%5Cfrac%7B1%7D%7B4%7D%20%3D%203.25)
So
![E = 2880*0.045*3.25](https://tex.z-dn.net/?f=E%20%3D%202880%2A0.045%2A3.25)
![E = 421.2](https://tex.z-dn.net/?f=E%20%3D%20421.2)
The interest earned is $421.2.
Yes so first the ratio is 3 (30/10)
so then you take the original ratio (9/10) and multiply the 9 by 3 (27)
30+27=57 so yes it is
In 0.6, the 6 is in the tenth's place. which means it is the same as 6/10.
now just simplify:
6/10 = 3/5
**
if it were 0.06, it would be 6/100 since 6 is in the hundredths place.
The answer is true i hope this helps
