Answer:

The correct option is D.

Step-by-step explanation:

The given expression is

(\frac{4}{7})^3

According to the property of exponent.

(\frac{a}{b})^n=\frac{a^n}{b^n}

Using this property the given expression can be written as

(\frac{4}{7})^3=\frac{4^3}{7^3}

(\frac{4}{7})^3=\frac{64}{343}

The simplified form of the given expression is \frac{64}{343}.

Therefore the correct option is D.

where c= starting amount

r=rate of change

x=time

so

y=45000(1-0.03)^x

y=45000-1350x
