At a certain real estate firm,realtors selling homes receive a commission of 7% for the first 140,000 of the selling price, and 5% for any amount exceeding 140,000. A realtor for the firm received 11,350 for selling a house. What was its selling price?

  • algebra - ,

    Let X be the selling price

    11,350 = 0.07*140,000 + 0.05 (X - 140,000)
    = 9,800 + 0.05 X - 7,000
    = 2,800 + 0.05 X
    0.05 X = 11,350 - 2,800 = 8,550
    Finish by completing the last step.
