For 2 it is slope 3 and y intercept (0,5)
For 3 it is slope y=-4x-5
Y = x - 1
y = -5 - 1
y = -6
(x, y) = (-5, -6)
y = x - 1
y = -3 - 1
y = -4
(x, y) = (-3, -4)
y = x - 1
y = 0 - 1
y = -1
(x, y) = (0, -1)
y = x - 1
y = 1 - 1
y = 0
(x, y) = (1, 0)
y = x - 1
y = 2 - 1
y = 1
(x, y) = (2, 1)
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.
