Simple Interest Rate Formula:
- 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]:
- [Interest] (Parenthesis) Add:
- [Interest] Evaluate exponents:
- [Interest] [Division Property of Equality] Isolate <em>P</em>:
- [Interest] Rewrite:
I’m guessing it’s 49 but I’m probably wrong sorry

Let x be the age of the father and y be the age of the son. As of today, he's 3 times older, so we have
10 years ago their ages were, respectively, x-10 and y-10, and the father was 5 times older:
So, we have the system
Using the first equation, we can substitute every occurrence of "x" with "3y" in the second equation:
So, the son is 20 years old, which means that the father is 60 years old.
Indeed, 10 years ago they were 10 and 50 years old, so the father was 5 times older.

Let x be the age of the grandfather and y the age of the granddaughter. We know that the grandfather is 10 times older:
He also is 54 years older:
Again, if we substitute x=10y in the second equation we have
