Answer: 18,000
Step-by-step explanation:
Liability policy:
![Insurance\ expense\ per\ month=(Prepaid\ Insurance\ for\ liability\ policy)/(Period\ of\ policy)](https://img.qammunity.org/2020/formulas/business/high-school/e10j2h34iih6s4iaaq2j8dnt5dqqn7xi6e.png)
![Insurance\ expense\ per\ month=(36,000)/(18)](https://img.qammunity.org/2020/formulas/business/high-school/p4ebkerdr78r90e0q5qc7ogh339r7yz7f8.png)
= 2,000
Insurance expense 2018:
= No. of months from 1 Jan 2018 to 31 Dec 2018 × Insurance expense per month
= 12 × 2,000
= 24,000
Prepaid insurance balance for liability policy on 31 Dec, 2018:
= Prepaid Insurance for liability policy - Insurance expense 2018
= 36,000 - 24,000
= 12,000
Crop damage policy:
![Insurance\ expense\ per\ month=(Prepaid\ Insurance\ for\ crop\ damage\ policy)/(Period\ of\ policy)](https://img.qammunity.org/2020/formulas/business/high-school/5sr3s28pvv7308glh4vnnlc8k9lbzgak9f.png)
![Insurance\ expense\ per\ month=(12,000)/(24)](https://img.qammunity.org/2020/formulas/business/high-school/weeemqxzex0lojmhfam0nos7fqgoy6kyol.png)
= 500
Insurance expense 2018:
= No. of months from 1 Jan 2018 to 31 Dec 2018 × Insurance expense per month
= 12 × 500
= 6,000
Prepaid insurance balance for crop damage policy on 31 Dec, 2018:
= Prepaid Insurance for crop damage policy - Insurance expense 2018
= 12,000 - 6,000
= 6,000
Therefore,
Total prepaid insurance balance on 31 Dec 2018:
= Prepaid insurance balance for liability policy on 31 Dec, 2018 + Prepaid insurance balance for crop damage policy on 31 Dec, 2018
= 12,000 + 6,000
= 18,000
