how do you calculate and write the accrual and prepayment on cash flow statement?

for example

1. the opening balance for interest paid is $0, the accrued interest during the month is $200. Do we assume interest paid is $200 or $0 on cash flow statement by the end of the month?
2. the opening balance for prepaid rent is $3000 for 3 month, which mean $1000 of rent has been used during the month, so do we only write $1000 as cash payment for rent?
3. the opening balance for supplies is $500, purchases during the month is $600. there are $700 left by the end of the month. In this case, do we write the amount of supplies we used($400) or the total amount $1100 on the cash flow statement?
