During vacation, Jimmy visits different beaches on an island, so he changes his place of lodging from time to time. The first 3 days he stays in a hostel, where he is charged $15 per night. The fourth and fifth days he stays in a cabin where he shares expenses with 2 of his friends, and they are charged $45 total per night. How much did Jimmy spend on lodging?
Thoughts? Step-by-step reasoning:
User
For the first 3 days, he pays 3 * $15 = $45. The next 2 days, he and his friends pay $45 * 2 = $90. Jimmy and his 2 friends pay $90 / 3 = $30 each. In total, Jimmy spent $45 + $30 = $75.
Thus, the answer is 75.
