At age 25, you invest $1,500 that earns 8 percent each year. How much money will you have at age 65? $_____ (no comma) 32586.78
AysviL [449]

Answer:

The Money Invested At age 25 earns more because it earns more Interest As compare to The Money Invested At age 40.

Step-by-step explanation:

According To the Question,

  • Given, A Person Invested $1,500 at Age of 25, With an 8% Per Annum Interest Rate.

Thus, The Money He will have at age of 65 would be, $1,500 * (1.08)^{40} = 32586.78$ . Here The Interest Earn in 40 Year Is 31086.78$.

  • And, the Same Person Invested $1,500 at Age of 40, With an 11% Per Annum Interest rate.

Thus, The Money He will have at age of 65 would be, $1,500 * (1.11)^{25} = $20378.20 . Here The Interest Earn in 25 Years Is 18878.20$.

⇒ Now, it is understood that the same amount invested for different periods of time & with a different interest rate, Since The Amount who get more Interest Would earn More. hence, The Money Invested At age 25 earns more because it earns more Interest As compare to The Money Invested At age 40.

Need help with these questions plz it would mean a lot :)
zhuklara [117]

Answer:

Awesome I actually remember this haha

Step-by-step explanation:

So first, find -2 and go down to it and put a dot. Then I would go up 7 and over 2 to the left and put a dot. On number 2, I would go up 3 (because it's a positive) and then put a dot. And for -6x, make it into slope intercept form, or -6 over 1x. So it should look like this; -6/1x. Then I would go down -6 from the dot where you marked 3 at, and over to the right 1 because you already used your negative on the 6. And I always drew arrows, to make sure they wee straight lines. I really hope this helps and is right! Good luck!
