Matt is going on a walk-a-thon. for every 1/2 mile he walks he gets $0.75. when he finished his walk he raised $3.75.how far did he walk?

Well....if he gets $0.75 for a half mile, he must get $1.50  for a whole mile......so...

3.75 / 1.50  = 2.5 miles

3.75/.75=5 number of "1/2 miles" he walked.

5/2=2.50 miles that Matt walked.Or,

1/2 mile X 2=.75 X 2

1 mile=$1.50 that Matt got

3.75/1.5=2.5 miles that Matt walked.
