Solve the inequality. graph the solution. z - 4.7 ≥ -1.6

Z - 4.7 > = -1.6
z > = -1.6 + 4.7
z > = 3.1

closed circle on 3.1, shading to the right

** it is a closed circle because there is an equal sign in the problem...it is shaded to the right because it is greater then

Num of plants = (original#ofplants)*(1.6)^t
