Verified answer

Subtract 0.075 from both sides:

0.03(30,000 - x) = 1439.925

Divide both sides by 0.03:

30,000 - x = 47,997.5

Subtract 30,000 from both sides:

-x = 17,997.5

Divide both sides by -1; x = -17,997.5

.075 + .03(30,000) - .03(x) = 1,440

.075 + 900 - .03x = 1440

.03x = .075 + 900 - 1440

.03x = -539.925

x = -17,997.5

75+30(30.000-X)=1,440,000

75+900,000-30X=1,440,000

30x=-540,000+75

x=18,000-2.5

x=17,997.5
