Answer:
[tex]4(x+18)=736\ \ \ \ \ \ \ \ \ \ \ \ (where\ x\ is\ cost\ of\ one\ ticket)\\\\x=\$166[/tex]
Step-by-step explanation:
Let cost of one ticket[tex]=\$x[/tex]
Travel insurance per ticket[tex]=\$18[/tex]
Total cost of one ticket[tex]=x+18[/tex]
[tex]cost\ of\ 4\ tickets=4\times cost\ of\ 1\ tickets=4\times (x+18)=4(x+18)\\\\Total\ Cost\ given=\$736\\\\Hence\ required\ expression:\ 4(x+18)=736[/tex]
[tex]4(x+18)=736\\\\x+18=\frac{736}{4}\\\\x+18=184\\\\x=184-18\\\\x=166\\\\Cost\ of\ one\ ticket=\$166[/tex]
