In 1991 , the moose population in a park was measured to be 4830 . By 1996 , the population was measured again to be 4230 . If the population continuss to change linearly: \( P(t)=\square \) for the moose population, \( P \), in terms of \( t \), the years since 1990 . B.) What doss your model predict the moose population to be in 2003 ?

If \( \frac{1}{2} x+3=\frac{3}{4}-x \), what is the value of \( x ? \)
