    Thirty years ago, Mr. and Mrs. Lopez purchased a house. On average, the value of the house has doubled every 6 years. If the house is worth $320,000 today, what did they pay for it 30 years ago?

    (A)$5,000
    (B)$10,000
    (C)$64,000
    (D)$160,000
    (E)$320,000*2^5

    Let the price that Mr. and Mrs. Lopez spent on the house be represented by the variable x. Then,

    2x- 6 years later

    4x-12 years later

    8x-18 years later

    16x-24 years later

    32x-30 years later

    32x=320000

    x=10,000
