A team of researchers is monitoring the population of crickets in a particular town. They do not know exactly how many crickets are remaining,
but the model they use represents the minimum number of crickets remaining in the town.
According to their model, the minimum number of the species remaining, in thousands, multiplies by 10 every month. The researchers
determine that right now, the population of crickets is at least 5 thousand. Once the minimum population reaches 1 million, measures are taken
to stop the increase in population.
If Prepresents the actual population of crickets in the town, in thousands, and trepresents the time, in months, which of the following systems
of inequalities can be used to determine the possible number of crickets in the town over time?
