cari is searching online for airline tickets. Two weeks​ ago, the cost to fly from denver to hartford was ​$225. Now the cost is ​$315. What is the percent​ increase? What would be the percent increase if the airline charges an additional​ $50 baggage fee with the new ticket​ price?

Answer 1

To find the percent increase, we need to calculate the difference between the new price and the old price, and then divide that difference by the old price and multiply by 100.

Percent increase = (New price - Old price) / Old price * 100

Percent increase = (315 - 225) / 225 * 100

Percent increase = 90 / 225 * 100

Percent increase = 0.4 * 100

Percent increase = 40%

If the airline charges an additional $50 baggage fee with the new ticket​ price, we would need to add this fee to the new price before calculating the percent increase.

New price with baggage fee = $315 + $50 = $365

Percent increase = (New price with baggage fee - Old price) / Old price * 100

Percent increase = (365 - 225) / 225 * 100

Percent increase = 140 / 225 * 100

Percent increase = 0.6222 * 100

Percent increase = 62.22%
