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

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

Explanation:

Let cost of one ticket
`=\$x`

Travel insurance per ticket
`=\$18`

Total cost of one ticket
`=x+18`

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

`4(x+18)=736\\\\x+18=(736)/(4)\\\\x+18=184\\\\x=184-18\\\\x=166\\\\Cost\ of\ one\ ticket=\$166`
