Help with Array question

Question

Need to create an array for this problem but am struggling.

 

Write a program for The Carefree Resort named ResortPrices that prompts the user to enter the number of days for a resort stay. Then display the price per night and the total price. Nightly rates are $200 for one or two nights; $180 for three or four nights; $160 for five, six, or seven nights; and $145 for eight nights or more.
