Answer: $315000
Step-by-step explanation:
From the information given in the question, the gross rental income that one will expect to receive for this space in the year after the lease expires goes thus:
= [(75% x 15) + (25% x 18)] x 20,000
= [(0.75 × 15) + (0.25 × 18)] × 20000
= (11.25 + 4.5) × 20000
= 15.75 × 20000
= 315,000
Therefore, the gross rental income is $315000
