Tom charges a fee of $100 a day to search for an item for the first 5 days and then $60 per day for every day after that. How much did it cost for him to look for an item for 10 days?
Please answer and provide answer explanation.
800
The first 5 days cost 5 * 100 = $500.

He gets 10 - 5 = 5 days on discount.

He paid 5 * 60 = $300 at the discounted rate.

So in total he pays 500 + 300 = $800.

.

Thus, the answer is 800
