Sam is moving into a new apartment. Before he moves i the land lord asks that he pays the first month's rent and a security deposit equal to 1.5 times the monthly rent. the total that Sam?

Sam's total payment to the landlord before moving in will include the first month's rent plus a security deposit. If we denote the monthly rent as "R," the security deposit will be 1.5 times that, or 1.5R. Therefore, the total amount Sam needs to pay is R + 1.5R, which equals 2.5R.
