Members of the debate team are travelling to a tournament, where they will stay in a hotel for 4 nights. The total cost for each member must be with in  of . Which of the hotels shown can they consider?

The correct answer is: it is clear that only Hotel A is the right option for the debate team.

Step by step solution:
For hotel A:
Cost of per person per night = $40
Cost of per person for 4 nights = $(40 × 4) = $160
For hotel B:
Cost of per person per night = $45
Cost of per person for 4 nights = $(45 × 4) = $180
For hotel C:
Cost of per person per night = $50
Cost of per person for 4 nights = $(50 × 4) = $200
We are given,
The total cost for each member must be within $20 and $175.
From the above calculations, it is clear that only Hotel A is the right option for the debate team.

This was a fairly simple problem of finding the total cost when the cost per night and the number of nights was already given.
