Samantha works in a bakery. the profit of cupcakes in dollars, after t weeks, is given by the function, c(t) = 0.1t3. the profit of cookies in dollars, after t weeks, is given by the function, k(t) = 5(1.07)t - 5. which function describes the total profit, m(t), at the bakery after t weeks? m(t) = 0.1t3 + 5(1.07)t - 5 m(t) = 0.1t3 + 5(1.07)t + 5 m(t) = 10t3 + 5(1.07)t - 5 m(t) = 0.1t3 - 5(1.07)t - 5
