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

Kadie bought 144 dougnuts for $80. her profit was $75 once she sold 100 dougnuts.
Which equation below represents Kadie's profit P, as a function of the number sold, n?
Sorry hadn't included all of the information before, does this anyhow help?
