In a recent year, the price of a gallon of heating oil in new england rose 3¢, dropped 4¢, and then rose 7¢. by how much did the price change during that period?

the price of oil has increased by $0.06 during the period

you would do 3-4=-1 and then -1+7= 6

so you would be left with a gain of $0.06

hope this helps! good luck!
