To determine how much rent tenant Jones will receive as a refund, we first need to understand the rental timeline and the applicable charges:
- Tenant Jones paid a full month's rent of $900 on June 1.
- Tenant Jones officially moved out on June 7.
- Tenant Smith took possession of the apartment on June 16.
Since tenant Jones is entitled to a refund for the days he did not occupy the apartment after moving out, we need to calculate the amount of rent attributable to those days.
From June 1 to June 7, tenant Jones occupied the apartment for 7 days. The rent for each day can be calculated by dividing the monthly rent by the number of days in the month:
\[ \text{Daily Rent} = \frac{900}{30} = 30 \text{ (dollars per day)} \]
Now, let's determine how many days tenant Jones paid for but did not occupy the apartment:
- June 1 to June 7: Jones was in the apartment - 7 days occupied.
- June 8 to June 30: These are the days that tenant Jones did not occupy the apartment - 23 days not occupied.
Now, we can calculate the total rent that corresponds to those 23 days:
\[ \text{Refund Amount} = \text{Daily Rent} \times \text{Days Not Occupied} \] \[ \text{Refund Amount} = 30 \times 23 = 690 \]
Therefore, once tenant Smith moves in, tenant Jones will receive a refund of $690.
