Answer:
$630,000
Step-by-step explanation:
The computation of the cash disbursements for September month is shown below:
= September purchase amount × paid percentage + August purchase amount × following month paid percentage
= $720,000 × 25% + $600,000 × 75%
= $180,000 + $450,000
= $630,000
We actually multiplied the purchase cost with the pay percentage so that the exact amount can be billed.
