Answer:
The company should deposit $74,954.02
Explanation:
We have an annuity with a variable installment with arithmetic progression.
[tex](a_1+\frac{d}{r} +d \times n) \times \frac{1-(1+r)^{-time} }{rate} - \frac{d \times n}{r}[/tex]
We plug our values:
C = 24,000
r = -2,000
r = 0.15
n = 6
And we get a PV of 74,954.02
We can build the table to verify:

(there is a 6 cent mistake due to rounding but without it It will be zero-out)
