Answer 2

9514 1404 393

Answer:

m +179.35 +154.80 = 400

m = 65.85

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

The girls still need to earn $65.85.
