max invests $6000 in a savings account for 3 years. the account pays compound interest at a rate of 1.5% per year for the first

madam [21]

Answer:

2.1%

Step-by-step explanation:

The formula for compound interest is given as:

$A=P(1+I)^n\\\\P-Principal \\A-amount\\i-compound \ interest \ rate$

Given the Principal amount as $6000, and the rate in the first two years as 1.5%:

$A=P(1+i)^n\\\\A_2=6000(1+0.015)^2\\\\A_2=6181.35$

We compound $A_2$ for 1 year at rate i to obtain $6311.16:

$A=P(1+i)^n, n=1, i=i, P=6181.35, A=6311.16\\\\6311.16=6181.35(1+i)^1\\\\\frac{6311.16}{6181.35}=(1+i)\\\\i=\frac{6311.16}{6181.35}-1\\\\i=0.02100$

Hence, the compound interest rate in the third year is 2.1%
