Bookstore costs $75 a day to keep open, and spends $10 for each book it sells. The store charges $15 for each book it sells. If n represents the number of books sold, which equation represents the cost function for this bookstore?
A.c=15n+75
b.c=75n+10
c.c=10n+75
d.c=75n+15

-
Cost=75+10n+15n
=75+25n

-
c = 75 + 10n
