What's the formula to figure out how much money you make on total rental payments over a period.
Say each month I rent out 2 cars, and get $50 for each. The length of the rental period is indefinite.
Jan, 2 cars = $100, $100 total
Feb, 2 cars = $100 + $100 for Jan's two cars, $200 total
Mar, 2 cars = $100 + $100 for jans + $100 for Febs, $300 total
How do I do this in a formula if I wanted to calculate, say 4 a month, at $50 payments, over the next 23 months. How much would I make?
I'm stuck
