A family buys 6 airline tickets online. The family buys travel insurance that costs $18 per ticket. The total cost is $1,140. Let x represent the price of one ticket. Write an equation for the total cost. Then find the price of one ticket Which equation represents this situation?
O A. 1.140 = 18(x+6)
OB. 1.140 = 6x + 18
0C18 = 6x + 1,140
OD 1.140 = 6(x + 18)
