Tim has just inherited £1000 and he decides not to invest it but rather to spend 10% of the remaining money each month. each month tim's saving thus reduce by a factor of 0.9 calculate, to the nearest integer, the amount remaining (in e) after 20 months. you may find it useful to first devise a formula for the amount remaining after n months. enter your answer, to the nearest integer and without units, in the box below.

£ 121.57

Step-by-step explanation:

As given in question,

Total amount inherited by Tim = £1000

He spends each month = 10 % of remaining money

savings reduced each month = 0.9 of remaining amount

So, the amount of money after one month = 0.9 x £1000

 amount of money remained after 2 months = 0.9 x 0.9 x £1000

amount of money remained after 3 months = 0.9 x 0.9 x 0.9 x £1000

Hence, the amount of money remained after the n months can be given by,

Hence, amount of money remained after 20 months can be given by,

            = £ 121.57

So, the amount of money remained after 20 months will be £ 121.57.
