Question

I don't get how to do this

Answer 1

Now, the average cost per night is 495....for 5 nights, it is (495 * 5) = 2475
and since the cost has tripled in the past 4 years....we can divide the regular cost by 3 to find out how much it would have cost 4 years ago
2475/3 = 825..thats for a 5 night stay 4 yrs ago

so the difference is : 2475 - 825 = 1650
