Answer:
It is $66.50 cheaper to purchase a return trip ticket than it is to purchase 2 one-way tickets.
Step-by-step explanation:
It is asking us how much does 2 one-way tickets costs as opposed to a return trip ticket. First, let's figure out how much does 2 one-way tickets cost.
Equation:
287.75 x 2 = 575.50
2 one-way tickets cost $575.50.
Then, to find the difference, subtract the return trip cost from the two one-way tickets.
Equation: 575.50 - 509.00 = 66.50
The difference between the two is $66.5
Conclusion: It is $66.50 cheaper to purchase a return trip ticket than it is to purchase 2 one-way tickets.
I hope this helps!
