Final answer:
To calculate the adjusted cash balance on October 31, 2017 for Raines Corp., subtract the outstanding checks and NSF checks, deduct the service charge, and add deposits in transit and interest earned on checking.
Step-by-step explanation:
To calculate the adjusted cash balance on October 31, 2017, we need to consider the differences between the bank statement balance and Raines' book balance.
1. Start with the bank statement balance of $30,700.
2. Subtract outstanding checks of $4,200 and NSF checks of $400.
3. Deduct the service charge of $300.
4. Add deposits in transit of $3,100 and interest earned on checking of $100.
The adjusted cash balance on October 31, 2017 is calculated as follows: $30,700 - $4,200 - $400 - $300 + $3,100 + $100 = $29,900.
