96kg(0.454lb/kg) = 43.58lb

c = 3x + 125 = 3(43.58) + 125 = \$255.75 (answer A)

(4x + 280) - (3x + 125) =

4x + 280 - 3x - 125 =

W = 4(259) + 280 = \$1316

F = 3(259) + 125 = \$902

difference is 1316 - 902 = \$414 (answer C)

W = 4(401) + 280 = \$1884

F = 3(401) + 125 = \$1328

difference is 1884 - 1328 = \$556 (answer C)

1) 96 * 0.454 * 3 + 125

#2) (4x + 280) - (3x + 125) = (4x - 3x) + (280 - 125) =

#3) 259 * (4x - 3x) + (280 - 125)

#4) 401 * (4x - 3x) + (280 - 125)

Simple rearrangement of the terms will give you the solution. Now that I've show you how, you just have to complete the final basic math.
