D= 1.78t^3-6.02t^2+ 752t+ 6701

where t is the number of years since 1983. In what year was 14.3 billion of private donations allocated to education?

(My main problems were location the real zeros on the Ti-84 graphing calculator of which I could only find one line on the graph. Also I'm not sure if when I subtract 6701 from 14.3 billion if I am suppose to move the decimal back one for remaining numbers. Ex. being 1.78t^3 to 0.178t^3.)

Thanks in advance.
