The information given about the probability shows that the expected maintenance cost is $22950.
How to calculate the cost?
From the information given, the repair hours and the probability are given.
In this case, the maintenance cost will be:
= (8 × 0.05) + (10 × 0.12) + (12 × 0.15) + (14 × 0.32) + (15 × 0.22) + (17 × 0.14) × $1700
= 13.50 × $1700
= $22950
In conclusion, the correct option is D.
