20 years old.
Step-by-step explanation:
Go backwards in the equation.
24/3 = 8
8+12
= 20
2/5(10)+3(6)-6
4+18-6
22-6
16

Answer: The initial amount in the account = $3600
Step-by-step explanation:
Since we have given that
The amount of money in a savings account after t years is represented by the function
As we know the formula "Compound Interest" :
So, According to our question,
Rate of interest = 0.35 = 35%
So, equate the both the equations , we get that
Hence, The initial amount in the account = $3600
First consider (x+c)^2 where c is just a random constant. if we expand this by foil (which is distributive property twice), we get x^2 + 2cx+ c^2. we want to find c^2 and to do that, we can first find c. we can find c by looking at the 2cx term. this term should match with 12x, so therefore 2c = 12 so c = 6. this also implies that c^2 = 36.
note that for this problem i was working backwards which is a very powerful problem solving tool: start with what you want to attain, and then see how you can go from where you are now to get to your destination.
let me know if you have any questions!!!
