Lebron most yards for each yard he charges $5.50 for the use of his mower and $3.50 for the use of his trimmer in addition lebron charges $5 an hour to mow and $6.50 an hour to trip lebron both mows and trims mr. johnson's lawn using his own mower and trimmer he takes twice as long to mow as he does to trim if he earns $25.50 a day how many hours did he earn

  LeBron trimmed for 1 hour and mowed for 2 hours

Step-by-step explanation:

Let t represent the number hours LeBron trimmed. Let m represent the number of hours LeBron mowed. The problem statement tells us two relationships:

  m = 2t . . . . . LeBron spent twice as many hours mowing as trimming

  (5.50 +5.00m) + (3.50 +6.50t) = 25.50

Substituting for m and collecting terms, we have

  9.00 + 16.50t = 25.50

  16.50t = 16.50

  t = 1

  m = 2·1 = 2

LeBron spent 1 hour trimming and 2 hours mowing.
