Answer 1

8 A television quiz show takes place every day. On day 1 the prize money is $1000. If this is not won
the prize money is increased for day 2. The prize money is increased in a similar way every day until
it is won. The television company considered the following two different models for increasing the
prize money.
Model 1: Increase the prize money by $1000 each day.
Model 2: Increase the prize money by 10% each day.
On each day that the prize money is not won the television company makes a donation to charity. The
amount donated is 5% of the value of the prize on that day. After 40 days the prize money has still
not been won. Calculate the total amount donated to charity
