mr jones estimates his profit starting in 2006 will be given by the formula p=7t^214t+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

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
