$223
To get this answer, first you have to take out the hotel costs out of the total costs. To do this, first find the actual amount the hotel costs. Multiply 175 by 3 as it says it is 175 for both people. This gives you 525.
Now that you have the hotel amount, subtract that from 971 to get 446. However, that is the cost for two people, so you need to divide that by two to get the individual cost of $223.
Hope this helps!
