drews neighbor pays him $35 to mow her lawn and she always gives him a 20% tip. he decides to mow the lawn with his freind and split the earnings evenly. how much money will each of them make?
[35 + .20 (35) ] / 2 = [ 35 + 7 ] / 2 = 42 / 2 = $21 each
20/100 of 35$ : 0.2*35=7 so 7/2=3.5
So 3.5$ you and 3.5$ your friend
