Answer 2

Givens

• The family buys 4 airline tickets online.
• The travel insurance costs $19 per ticket.
• The total cost is $752.

A.

An equation that models this problem could be

`4(x+19)=752`

Basically, we know that the insurance costs $19 which represents an additional costs after the price per ticket, that's why we need to add them. Then, we know that the familiy bought 4 tickes, that's why we multiply by 4, and finally, the total cost must be equal to 752, according to the problem.

B.

To find the price of one ticket, we just need to solve the equation for
`x`

`4(x+19)=752\\4x+76=752\\4x=752-76\\x=(676)/(4)\\ x=169`

Therefore, one ticket costs $169.
