Final answer:
An inequality of $18 < $10 + $2.95d can be used to determine the number of days The Fairmont is a better deal. After simplifying, the inequality is d > $8 / $2.95. Calculate this to find the minimum number of days for The Fairmont to be more cost-effective.
Step-by-step explanation:
To determine the number of days (d) you would need to stay at a hotel for The Fairmont to be a better deal than Park Street Hotel, we can set up an inequality. The cost at Park Street Hotel with a $10 resort fee plus $2.95 per day for wireless internet use is $10 + $2.95d. For The Fairmont, the cost with an $18 resort fee including free wireless internet is just $18.
So, The Fairmont will be a better deal if its total cost is less than the total cost at Park Street Hotel:
$18 < $10 + $2.95d
Now, subtract $10 from both sides of the inequality:
$8 < $2.95d
Finally, divide both sides by $2.95 to find the number of days:
d > $8 / $2.95
After calculating, you will find the minimum number of days you need to stay for The Fairmont to be the better deal.
