Answer :
Using linear functions, it is found that the two stocks will be nearly equal in 30 months.
What is a linear function?
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
Each of the stocks can be modeled by these following functions:
- S1(t) = 39.63 + 0.3t.
- S2(t) = 24.45 + 0.8t.
They will be equal when:
S1(t) = S2(t).
Hence:
39.63 + 0.3t = 24.45 + 0.8t
0.5t = 15.18
t = 15.18/0.5
t = 30.36.
Rounding, approximately 30 months.
