Calculate in math the present value for offer $1$ and $2.$ Show normal work please I can't read the others

Offer I. The buyer in this case was Smythe Manufacturing. They offered Dr$.$ Miller $$2$

million now plus $$100,000$ each year beginning at the end of year six and continuing

through the end of year fifteen. You are Dr$.$ Miller$$s financial advisor and you feel that given the associated risks to this payment stream, a $10\%$ interest $($discount$)$ rate should be used to determine the present value of the offer.

Offer II$.$ The buyer in this case was Brouwer Pharmaceutical. They offered $40$ percent

of their gross profit on the product for the next four years, with payments beginning at the end of the first year. Brouwer$$s gross profit margin was $60\%.$ Sales in year one were

projected to be $$3$ million and are forecasted to grow by $30$ percent each year thereafter.

You are Dr$.$ Miller$$s financial advisor and you feel that given the associated risks to this payment stream, an $8\%$ interest $($discount$)$ rate should be used to determine the present value of the offer.
