Indicate the amount (if any) that Josh can deduct as an ordinary and necessary business deduction in each of the following situations. (Leave no answers blank. Enter zero if applicable.)

a. Josh borrowed $56,000 from First State Bank using his business assets as collateral. He used the money to buy City of Blanksville bonds. Over the course of a year, Josh paid interest of $12,500 on the borrowed funds, but he received $8,100 of interest on the bonds.

b. Josh purchased a piece of land for $93,500 in order to get a location to expand his business. He also paid $11,700 to construct a new driveway for access to the property.

c. This year Josh paid $22,200 to employ the mayors son in the business. Josh would typically pay an employee with these responsibilities about $20,900, but the mayor assured Josh that after his son was hired, some city business would be coming his way.

d. Josh paid his brother, a mechanic, $3,350 to install a robotic machine for Joshs business. The amount he paid to his brother is comparable to what he would have paid to an unrelated person to do the same work. Once the installation was completed by his brother, Josh began calibrating the machine for operation. However, by the end of the year, he had not started using the machine in his business.
