Simple Interest Rate Formula: ![\displaystyle A = P(1 + r)^t](https://tex.z-dn.net/?f=%5Cdisplaystyle%20A%20%3D%20P%281%20%2B%20r%29%5Et)
- A is final amount
- P is principle amount
- r is rate
- t is time
Step-by-step explanation:
<u>Step 1: Define</u>
A = 960
r = 0.12
t = 5
<u>Step 2: Solve for </u><em><u>P</u></em>
- Substitute in variables [Simple Interest Rate Formula]:
![\displaystyle 960 = P(1 + 0.12)^5](https://tex.z-dn.net/?f=%5Cdisplaystyle%20960%20%3D%20P%281%20%2B%200.12%29%5E5)
- [Interest] (Parenthesis) Add:
![\displaystyle 960 = P(1.12)^5](https://tex.z-dn.net/?f=%5Cdisplaystyle%20960%20%3D%20P%281.12%29%5E5)
- [Interest] Evaluate exponents:
![\displaystyle 960 = P(1.76234)](https://tex.z-dn.net/?f=%5Cdisplaystyle%20960%20%3D%20P%281.76234%29)
- [Interest] [Division Property of Equality] Isolate <em>P</em>:
![\displaystyle 544.73 = P](https://tex.z-dn.net/?f=%5Cdisplaystyle%20544.73%20%3D%20P)
- [Interest] Rewrite:
![\displaystyle P = 544.73](https://tex.z-dn.net/?f=%5Cdisplaystyle%20P%20%3D%20544.73)
Answer:
it'll be A
Step-by-step explanation:
each bar is equals one X and each square must equal one number, plus remember doing this question before (also the signs inside the two units to the left are negative )
