Let the cost of tie be N.
Since shirt is 5x the cost of a tie, it is 5N.
5N-N=4N
Since the difference between cost of shirt and tie is $36
4N=$36
N=$9
Since he bought a tie and a shirt,
N+5N= 6N
And since 1N = $9
6N = $54

5 times means 5 units for shirt and 1 unit for tie. Your model is drawn wrongly.
