Sara loves to go hiking. this week she hiked 3 miles on monday, 4 miles on tuesday, and 3 miles on thursday. last week sara hiked 8 miles. how many more miles did sara hike this week than last week?

Distance hiked by Sara last week = 8 miles
Distance hiked by Sara on Monday this week = 3 miles
Distance hiked by Sara on Tuesday this week = 4 miles
Distance hiked by Sara on Thursday this week = 3 miles
So
Total distance hiked by Sara this week = (3 + 4 + 3) miles
                                                              = 10 miles
The number of more miles hiked by Sara this week = (10 - 8) miles
                                                                                  = 2 miles

Ican't do any of the other stuff, but i can get you started. the answer, i believe, is $2.50.
