By examining the line plot, we find the number with the maximum number of crosses or occurrences. This gives the mode of the data set. We find the smallest and the largest number from the data set and find their difference and this difference is the range of the given data set.
R= 98600/30 $/day
R= 9860/3
Debt= 1200000-98600
=1101400
Debt= R•days
1101400=9860/3•(days)
335.1= days
336 days because you can't have a partial day and 335 days would leave $367 of debt still.
It would take the company 336 more days to earn back it's investment.
