I have $150,000,000 and planning on purchasing an item that costs $200,000.
I can only buy one at a time and every time I purchase this item the price increases by $1,800.
How many times can I purchase this item?
:
To cut down on typing do this in 1000's
:
Let n = no. of items you can buy with 150 million
Assuming the 1st one is 200k, 1800 added each one after that
:
200n + 1.8(n-1) = 150000
200n + 1.8n - 1.8 = 150000
201.8n = 150000 + 1.8
n =
n ~ 743 times
