We need to calculate the new price of denim jacket after 1 year.
00:04
So we need to increase the initial price by the given annual inflation rate.
00:09
We'll then determine the number of jacket dalton can purchase with her deposit after 1 year and calculate the real interest rate.
00:17
So given to us initial deposit $4000, initial purchasing power is 200 denim jackets.
00:51
So then first one 0 % inflation.
01:06
So under it new price is evaluated as initial price which is $20.
01:15
Wherein we multiply it by 1 to which we add inflation rate which is 0.
01:20
Equating it we get the value to be $20 no change.
01:25
Then number of jackets it is evaluated as initial deposit which is $4000 divided by new price it is $20.
01:43
We get the value to be 200 jackets.
01:49
And then real interest rate it is evaluated as number of jackets after 1 year which is 200.
02:07
Wherein we subtract number of jackets initially this is also 200 divided by number of jackets initially which is 200 multiplied by 100.
02:18
Equating it we get the value to be 0%.
02:22
Next 5 % inflation...
