mr jones estimates his profit starting in 2006 will be given by the formula p=7t^2-14t+10 where t is number of years and p is the profit.if this formula is correct,when will mr.jones have a profit of more than $1000. please help

  • algebra1 - ,

    Just plug in the numbers and solve for t:

    7t^2 - 14t + 10 > 1000
    7t^2 - 14t - 990 > 0

    The roots of 7t^2 - 14t - 900 = 0 are

    t = (7±√6979)/7 = -10.934,12.934

    So, t>12.934 will produce > 1000 profit
    That would be in 2019
