Question

Shelley is searching online for airline tickets. Two weeks​ ago, the cost to fly from Orlando to Hartford was ​$200. Now the cost is ​$280. 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

#1

• Old price=200$
• New price=280$
• Increase=280-200=80$

Rate of increase (Percent increase)

`\\ \tt\hookrightarrow (80)/(200)* 100`

`\\ \tt\hookrightarrow 40\%`

#2

• New price=280+50=330$
• Increase=330-200=130$

Percent increase:-

`\\ \tt\hookrightarrow (130)/(200)(100)`

`\\ \tt\hookrightarrow 65\%`

Answer 2

What is the percent​ increase from $200 to $280?

• 
  `(280)/(200) *100 -100` →
  `140 -100` → 40%

There was 40% increase from $200 to $280

What would be the percent increase if the airline charges an additional​ $50 baggage fee with the new ticket​ price?

• increase with baggage fee:

• new ticket cost + baggage free

• 280 + 50

• $330

• 
  `(330)/(200) *100 - 100` → 165% - 100% → 65%

There was 65% increase with the baggage fee.
