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

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

• $\frac{280}{200} *100 -100$  → $140 -100$ → 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

• $\frac{330}{200} *100 - 100$  → 165% - 100% → 65%

There was 65% increase with the baggage fee.

Answer 2

#1

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

Rate of increase (Percent increase)

$\\ \tt\hookrightarrow \dfrac{80}{200}\times 100$

$\\ \tt\hookrightarrow 40\%$

#2

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

Percent increase:-

$\\ \tt\hookrightarrow \dfrac{130}{200}(100)$

$\\ \tt\hookrightarrow 65\%$
