A family buys 4 airline tickets online. The family buys travel insurance that cost $19 per ticket. the total cost is $688. Let x represent the price of one ticket. Write an equation for the total cost. then find the price of one ticket

Answer: 4x + 76 = 688, $153 per ticket

Step-by-step explanation:

there are 4 tickets but you don't know the price of the tickets. Let x represent the price. Insurance costs $19. They got insurance ($19) on all 4 tickets (19 x 4) to get a insurance total of $76.

To get the price of one ticket we need to solve the equation.

4x + 76 = 688

subtract 76 from both sides.

4x = 612

divide by 4.

x = 153

each ticket costs $153
