Final answer:
Desi can deduct $550 for the business use of his home office by multiplying the area of his office (110 square feet) by the standard rate of $5 per square foot using the simplified method.
Step-by-step explanation:
Desi is eligible to deduct expenses for the business use of his home office using the simplified method.
This method assigns a standard deduction of $5 per square foot for the area of your home used exclusively for business, with a maximum of 300 square feet.
As Desi's office measures 110 square feet, we multiply 110 by $5 to calculate the deduction amount.
110 square feet x $5 per square foot = $550
Therefore, Desi can deduct $550 for the business use of his home office using the simplified method.
