For me, the answer is M = k/ O + S.
Explanation:
The given statement is an example of Inverse Variation. A type of variation that deals with the property, as the value of x increases, y decreases, and vice versa. So, the equation will be y = k/x can be expressed as y varies inversely as x or y is inversely proportional to x.
Given Statement:
The money M varies inversely as the sum of its online business income O and its salary S.
Solution:
M = y
O+S = x
- (the representation for the 'sum of its online business income and it's salary'
- k is the constant of proportionality.
Therefore, the equation of variation is
M = k / O + S.
