Don tracked the price of gas for several months. in january gas cost $2.65, in february the price had risen $0.56, in march decreased $0.23, in april risen $1.02, and in may decreased $0.48. by how many dollars has the price of gas changed from january to may?

Starting price is 2.65, increased by .56

2.65+.56=3.21

Price is 3.21, decreased by .23

3.21-.23=2.98

Price is 2.98, increased by 1.02

2.98+1.02= 4

Price is 4, decreased by .48

4-.48=3.52

Now find the difference from the starting price (January) from the end price (May)

3.52-2.65=.87

The difference from gas prices is $.87
