Answer:
Rent is $2400
utilities other than cellphone is $625
Total home office expenses is $3025
Explanation:
firstly we need to calculate the percentage of how much in total does the office take in the apartment so we will say (300 square feet/1200 square feet) x 100
which is 25% so then to get the rental expense of the office we will say :
25%x$9600 = $2400 we say 25% which is office space in the apartment multiplied by the total apartment rental to get the office rent expense.
Then for the utilities we will say 25%x$2500 = $625 we multiply like this because the office uses 25% of all the apartment utilities .
thereafter the total home office expenses is the sum of both the rental office expense plus the the utilities other than telephone for the home office expense:
$625 + $2400 = $3025 then we get total home office expenses.
