Answer:
req time=2.5 year
Step-by-step explanation:
simple interest=[tex]\frac{P\times R\times T}{100}[/tex]
where P=principle
R=rate of interest
T=time
totel amount= principle+simple interest
simple interest=totel amount-principles
simple interest=$575-$500=$75
ac/ques, 75=[tex]\frac{500\times 6\times T}{100}[/tex]
75=[tex]30\timesT[/tex]
T=2.5 year
