Question

A family buys 4 airline tickets online. The family buys travel insurance that costs ​$18 per ticket. The total cost is ​$736. Let x represent the price of one ticket. Write an equation for the total cost. Then find the price of one ticket.

Answer 1

Answer:

$4(x+18)=736\ \ \ \ \ \ \ \ \ \ \ \ (where\ x\ is\ cost\ of\ one\ ticket)\\\\x=\ 166$

Step-by-step explanation:

Let cost of one ticket$=\ x$

Travel insurance per ticket$=\ 18$

Total cost of one ticket$=x+18$

$cost\ of\ 4\ tickets=4\times cost\ of\ 1\ tickets=4\times (x+18)=4(x+18)\\\\Total\ Cost\ given=\ 736\\\\Hence\ required\ expression:\ 4(x+18)=736$

$4(x+18)=736\\\\x+18=\frac{736}{4}\\\\x+18=184\\\\x=184-18\\\\x=166\\\\Cost\ of\ one\ ticket=\ 166$
