Question

Colleen is searching online for airline tickets. Two weeks ago, the cost to fly from Boston to Hartford was 250$. Now the cost is 330$. 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

32%

52%

Step-by-step explanation

Step 1

let

original cost=$250

new cost=330

to find the percentage of increasing

`\begin{gathered} \frac{new\text{ price}}{\text{original price}}\cdot100=(330)/(250)\cdot100=1.32 \\ \\ 1.32\Rightarrow132\text{ per cent} \end{gathered}`

it means the increase is 32%

Step 2

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

the new price is= 330+50

new price(fee included)=380

and do the same:

`\frac{new\text{ price}}{\text{original price}}\cdot100=(380)/(250)\cdot100=1.52\cdot100=152`

the new price is 152% of the original, it measn the increase is

52%

I hope this helps you
