  m +179.35 +154.80 = 400

  m = 65.85

Step-by-step explanation:

A suitable equation is one that adds the amounts they have to the amount they need and makes that total be $400. (All amounts in dollars.)

  m +179.35 +154.80 = 400 . . . an equation

  m = 400 -334.15 . . . . subtract 334.15 from both sides

  m = 65.85 . . . . . . . . . simplify; the value of m
