which tells you that
, so in fact
Attached is an image demonstrating why the identity is true.
Step-by-step explanation:
M = L + rL
a.
L = $63.80
M = $121.80
need to find r
121.80 = 63.80 + r×63.80
58 = r×63.80
r = 58/63.80 = 0.91 = 91%
b.
L = $65
M = $146.25
need to find r
146.25 = 65 + r×65
81.25 = r×65
r = 81.25/65 = 1.25 = 125%
