Answer

Q - (87) (a) T(x)=75x if 0≤x≤2 T (x)=50(x-2)+150 if x>2 (b) $150, $200, $300 (c ) The cost for staying at the hotel.

Work Step by Step

Q - (87) (a) T(x)=75x if 0≤x≤2 T (x)=50(x-2)+150 if x>2 (b) When x = 2 T(x)=75x Now substitute the value of x to the above equation T(2)=75 ( 2) = 150 When x = 3 T (x)=50(x-2)+150 Now substitute the value of x to the above equation T (x)=50(3-2)+150 = 200 When x = 5 T (x)=50(x-2)+150 Now substitute the value of x to the above equation T (x)=50(5-2)+150 = 300 (c ) The cost for staying at the hotel (When customers stay 2 nights or more than 2 nights)
