69*.9 + 8=70.1, taking the iron curtain to be 13.2/2.4(taking keys as 2.4 instead of 1.8 because scm not paypal) = 5.5

70.1+5.5 = 75.6, will round to 76.

76 keys.

So we have sales at 30, 50, 64, and 76

I want to consider the 30 and 50 key sales outliers but due to a mods advice i will form a range with the 50keys and 64 keys sales.
