My question is: Twenty people pre-bought plane tickets at a price of $155 per ticket. Thirty people bought their plane tickets at the gate and they each paid $200 for their ticket. How many more dollars did the people at the gate pay for their tickets than those passengers that pre-bought their tickets? Your thoughts:
Pre - bought: 20 people * $155 = $3100. Gate bought: 30 people * $200 = $6000. $6000 - $3100 = $2900. The passengers that paid at the gate paid $2900 more dollars than those who pre - bought their tickets. The final answer: 2900.
