Deb is searching airline tickets. Two weeks ago, the cost to fly to Orlando to Denver was $220. Now the cost is $370. What is the percent increase? What would be the percent increase if the airline charges $50 baggage fee with the new ticket price

68.18% and 90.91%

Step-by-step explanation:

Deb is searching for airline tickets. Two weeks ago, the cost to fly from Orlando to Denver was $220 while the cost now is $370.

Price two weeks ago= $220

Price as at today= $370

Increase in price =$370-$220=$150

Percentage increase= 150/ 220 × 100

=0.6818 × 100 = 68.18%

If the airline charges $50 fee for baggage with the new ticket price, the total cost will now be

$370 + $50= $420

Increase= $420 - $220 = $200

Percentage increase:

200/220 × 100

= 0.9091 × 100

= 90.91%

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
