This one will be a bit more straight forward
For this we will just reuse the same formula with a slightly less salary at 85k NZD (49847 USD) then we just put it into the formula
(85,000 * ( 1 - 0.2 )) / 12 this gives us 5666 NZD (3322 USD)
For this time around I had to get a slightly cheaper house so that we can keep the costs manageable. That search has resulted in this house.
Now we just input cost 440 * 4 to get the monthly cost of 1760 NZD (1037 USD)
Though I am certain I could afford a car that isn't interesting so we are using public transport. BUSES!!! The ticket cost for the Christchurch system is 2$ per ticket then we would need to use the bus 2 times a day for 30 days in a month to get 120 NZD (70 USD)
