Final answer:
The equation that represents this situation is 4x + 19 = 752.
Step-by-step explanation:
The equation that represents this situation is option A. 4x + 19 = 752.
To find the equation, let's break down the information given. We know that there are 4 airline tickets and the total cost is $752. The family also buys travel insurance that costs $19 per ticket. Let's represent the price of one ticket as 'x'.
The total cost of the 4 airline tickets is 4 times the price of one ticket, which can be written as 4x. Adding the cost of travel insurance for each ticket, the equation becomes 4x + 19 = 752.
