Answer:
-7.1
Step-by-step explanation:
increased=150%=0.75
original price =100%
100%*0.75/150
=$0.5
The difference is 4 degrees
If its difficult for you to subtract negatives just switch them to a positive 1 and 5 now subtract 1 from 5=4 and because the measure being used is degrees the final answer would be 4 degrees.
