Camille bought 120 doughnuts for $60.00. Her profit was $48.00 once she sold 80 doughnuts. Write an equation that represents Camille’s profit (P), as a function of the number of doughnuts sold, n.
If she bought 120 doughnuts for $60....she must have paid 60/120 dollars = .50 for each
If she sold 80 doughnuts for $48 she made 48/80 = 6/10 dollars = .60 for each doughnut sold
So.....the profit per doughnut sold, n, is represented by
P(x) = .10n
