3) An investor buys a bond for £1000It pays £300 at the end of the first year, butpayments at the end of each subsequent yearare 20% less than the previous payment...

HARD Question:7) An insurance policy salesman has managed to snagan amazing contact with his employer...

He'll be selling insurance policies and he'll earncommission payments on each policy he sellsFor each policy that he sells, the employer agrees to payhim £75 that month, and then £60 the following month,and so on... (each new payment being 80% of the previous payment)

He started work in Jan 2016 and he sold one policythat month......but, being quite lazy, he's decided he's only going tosell one policy each month, and then play Playstationfor the rest of that month!

a) Work out how much commission he earns in total in Jan 2017

Actually, in August 2017, he's going on holiday for thewhole month!b) Re­calculate his commission for Jan 2018

HARD Question:8) A teacher decided to quit and invest in property instead

In 2008 he purchased an acre of land, which heplanted with Camelia Senensis (Darjeeling ­ I meant,proper­tea, not property).In the summer of 2009, this produced a crop of45 kg of top grade tea. He knows that the yield fromthis planation will increase by 15% year on year...

But, in 2009, he purchased a second acre and plantedit in the same way ­ and he did so again in 2010 etc
