4. An account was opened with $3000 earning 5%
Natalka [10]
P= $3000
R=5%
Amount=$3300

SI = A-P
= 3300-3000=300.
Therefore SI is $300.


SI = PRT/100

300 = 3000x5xT/100
300= 150T
T = 300/150
T = 2


Therefore . The account has been earning for 2 years

By the end of year 8, demarco and tanya would have to pay a final payout of $120,887. $130,900. $143,152. $154,768.
Lubov Fominskaja [6]

If a person invests $50 in a business and gets a percentage increase of 10%, then he would have $55 as his final payout.

<h3>What is an Investment?</h3>

This refers to the financial activity where a person puts money or an asset into a business or venture to gain profit after a period of time.

Hence, we can see that since your question is incomplete as it does not include the initial amount of both Demarco and Tanya, then a final payout cannot be found.
