sorry .05*1000=50
Nah. I think it’s 100. But I’m having trouble concocting a genius explanation of why that is. I just crunched through the math, but there must be an elegant way to show WHY.
Those fractions resolve to 1/10th. 1000/10 = 100
Taylor, I think the “simplified math” is:
a/b1 x b1/b2 x b2/b3 x … x bn/c
In this case all of the b terms cancel out, because it could be written as a/c x b1/b1 x b2/b2 x b3/b3 … bn/bn
since b1/b1 = 1 and b2/b2 = 1 etc. you are left with a/c (1/10 in our case) x 1000 = 1000.
100
Taylor, you are today’s winner! Thank you Brent for your explanation.
One hundred – work backwards and you will understand.
