The revered Rossignol Brothers Investment Banking House 'goes

public' with an IPO (coincidentally) on the very same day you

receive a $12,000 signing bonus as their new employee. As part

of a "Rossie" profit-sharing plan, this dynamic company's new

equity issue is available to you (one time only!) at $100 per

share.If returns to Rossie equityholders are now expected to

average 17.5%(annually-stated, compounding on a weekly basis),

how many years will it take for your 'lump sum' t=0 investment

to provide the 25% down payment on that coveted $97,000 Viper?

2) What is the effective annual rate of return on Rossie stock?

Same question with 2 parts. Could you show me the steps how you solved it? Thank you.
