Numbers 5 and over round up to the nearest 10. Numbers like 164 would found to the nearest 10 of 160 because the last number (unit) is below 5, so it rounds down. I hope this helps but you can find tutorials on google good luck!

When you round to the nearest 10 you look at the ones place and see if it is greater or less than 5. If it is greater you round up if less than you leave it the same. For 100 you look at the 10s place and you do the same thing

​$4000 is deposited in an account that pays an APR of 8.4​% compounded annually. How long will it take for the balance to reach
patriot [66]

Answer: number of years that it will take for the balance to reach ​$120,000 is 42 years

Step-by-step explanation:

Initial amount deposited into the account is $4000. This means that the principal is $4000

P = 4000

It was compounded annually. This means that it was compounded once in a year. So

n = 1

The rate at which the principal was compounded is 8.4%. So

r = 8.4/100 = 0.084

Let the number of years that it will take for the balance to reach ​$120,000. It means that it was compounded for a total of t years.

Amount, A at the end of t years is $120,000

The formula for compound interest is

A = P(1+r/n)^nt

120000 = 4000(1 + 0.084/1)^1×t

120000/4000 = 1.084^t

30 = 1.084^t

t = 42 years
