As part of a sixth-grade class project, the teacher brings to class a large jar containing 200 gumballs of two different colors: red and green. Andy is asked to draw a sample of his own choosing and estimate the number of red gumballs in the jar. Andy draws a sample of 20 gumballs, of which 8 are red and 12 are green. Use Andy's sample to estimate the number of red gumballs in the jar. Approximately how many red gumballs are in the jar? Use whole numbers.
