Kadie bought 144 dougnuts for $80. her profit was $75 once she sold 100 dougnuts. What would be a equation for this?
A. P = 0.05n +80
B. P = 0.05n  80
C. P = 0.75n
D. P = 1.55n  80
Its D, but how do u get that answer, this is so confusing

P = $75
Expenses = $80
Profit = (price per doughnut sold)(n)  80
However, you have not given the selling price for each doughnut. $1.55 seems like a very expensive doughnut.
