The regular monthly rent at the Empty Arms Apartments is $800 per month. If Andrew signs a one-year lease, the rent is reduced to $700 and the security deposit is also reduced from $500 to $300. The lease also states that if Andrew terminates the agreement prior to one year, he must repay the entire rent reduction and the balance of the security deposit. ​ Suppose Andrew must move out at the beginning of the eighth month. What is the total amount he would owe the landlord, under the terms of the lease?
