Answer:
80
Step-by-step explanation:
As for the required reserve balance the information is provided as follows:
Total amount deposited by Jose = $400
Provided the reserve balance = 20%
Therefore, reserve balance from this payment = $400
20% = $80.
As it is not specified clearly, that this $400 is inclusive or exclusive of the reserve balance, it is assumed that reserve will be created out of such balance.
Therefore, reserve maintained from this $400 = $80 and the rest $400 - $80 = $320 will be usable freely, without any restrictions.
