Answer:

[tex]3\ years[/tex]

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=?\ years\\ P=\$600\\ A=\$600+\$45=\$645\\r=0.025[/tex]

substitute in the formula above  and solve for t

[tex]645=600(1+0.025t)[/tex]

[tex]t=[(645/600)-1]/0.025=3\ years[/tex]
