Explicit cost, Implicit cost or not needed to be reflected.

Tom total revenue from his cafe is 50000 per year, he bought a coffee machine costing $5000 with ($2000 of which is his savings which the bank gave him an interest rate of 5% and $3000 is a loan from the bank which the rates is 10%). If he work as a sales man he can earn $30000 /yr. What is his explicit and implicit cost.

I know that the (5% of 2000) is implict cost.
$30000 + (10% of 3000) is the explicit cost.

However i am confuse. Do i need to add the cost of the machine of $5000 to explicit or implicit cost? Or i don't have to place this value any where.
