I used an inflation calculator to find the inflation rate from 2020.
It said that if you bought something in 2020 for $1,200 it would cost $1,453.79 in 2024, which is a 21.1% increase.
So if you multiply $1,200 by 78.9% you get $946.80.
Then I just rounded to $950.
There are many inflation calculators out there. Some give slightly different numbers.
Here's the one I used.
