Answer:
To calculate the rate of change (decrease or increase), use the formula [(final value - initial value)/initial value] *100.
Carrie searches online for airline tickets. Two weeks ago, the cost of a flight from Hartford to Denver was $210; now it's $350.
What is the percentage increase?
[(350-210)/210]*100=66.6666=67%
What would be the percentage increase if the airline charged $50 in additional baggage fees with the new ticket price?
new ticket price: $350
additional baggage fees:$50
total price: $400
% increase over old price :
[(400-210)/210]*100=90.476..=90.5%
