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:
