How to calculate cost per every day(cost hotel + cost flight

I need to make database design relations to calculate cost per tour for touristes in egypt

Flight cost + hotel cost per every day for person based on flight date

Suppose I have flight on date 23/06/2017 from amesterdam to egypt

And from cairo to amesterdam in 26/06/2017 will return back

So that calculation will be as following :

Table tour

1 Tour1

2 Tour2

3 Tour3

Table Tour Duration

Tour1 3 days

Tour2 6 days

Table Tour Duration Details

Day flight Hotel

Day1 amesterdam to cairo Hilton

Day2 Cairo to aswan Hilton

Day3 Cairo to amsterdam

From 23/06/2017 to 26/06/2017

Table cost Per day

Day1 500 25

Day2 300 25

Day3 500

Table fligh data

Tour1 23/06/2017 26/06/2017 1350

Tour2 01/07/2017 07/07/2017 1425 (5 * 25 + 1300)

25 represent cost accomodation per night in hilton hotel

500 represent cost flight from cairo amsterdam ,amsterdam to cairo

300 represent cost per flight from cairo to aswan

How to design table relations to calculate cost per every day(cost hotel + cost flight) depending on flight date ?
