Carrie wants to take a trip to New York. She can get a 20% discount on an $850 flight with Delta Airlines. She can also save 30% off an $1100 flight with United Airlines. How much money would she save by choosing the cheapest flight? Think carefully first, then make a decision:
The discount for the Delta flight would come to $850 * 0.20 = $170. The final price of the Delta flight would come to $850 - $170 = $680. The discount of the United flight would come to $1100 * 0.30 = $330. The final price of the United flight would come to $1100 - $330 = $770. The Delta flight would be cheaper than the United flight by $770 - $680 = $90. So, the answer is 90.
