Having completed your first few tasks, you move now to a portion of the lab where important bacteria are being grown. Based on the data collected, you have determined that the population of this bacteria in the range measured can be modeled as $A(t)=195(1\mathrm{.}21{)}^t,$ where $t$ is given in days. To the nearest whole number, what will the bacteria population be after $4$ days?

The bacteria population will be
