Question

A family buys 5 airline tickets online. The family buys travel insurance that costs ​$16 per ticket. The total cost is ​$840. Let x represent the price of one ticket. Write an equation for the total cost. Then find the price of one ticket.

Answer 1

If travel insurance for 1 ticket = $16
Travel insurance for 5 tickets = $16 * 5 = $80
If the price of 1 ticket = x
The price of 5 tickets = 5 * x = 5x
The total cost of tickets and insurance = $840
5x + 80 = 840
Subtract 80 from both sides
5x + 80 - 80 = 840 - 80
5x = 760
Divide both sides by 5
5x/5 = 760/5
x = 152
The price of 1 ticket is $152
Let’s check if x = 152 is a solution for 5x + 80 = 840
5(152) + 80 = 840
760 + 80 = 840
840 = 840
