Answer:

D.A(n) = 250 + (n – 1)(0.03 • 250); $347.50

Step-by-step explanation:

we know that

The simple interest formula is equal to

[tex]A=P(1+rt)[/tex]

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

[tex]t=(14-1)=13\ years\\ P=\$250\\r=0.03[/tex]

substitute in the formula above

[tex]A=\$250(1+0.03*13)[/tex]

[tex]A=\$250(1.39)=\$347.50[/tex]
