Frank bought lunch for $5.60 at a diner. he spent $2.00 to ride the bus to the mall and back, and spent $6.50 while he was at the mall. his friend bill paid him back $5.00 that he had borrowed last week. if frank arrived at home with $10.50 in his pocket, how much did he have when her left home that morning? ( i have to write a thing of how much like a line of how much he spent and earned. )
