Jessie is purchasing a new car at a dealership that is offering a discount of 15%. The dealership is also offering an incentive of $2500 off the listed price. Let x represent the original price of the new car. 77. Write a function d(x) that represents the price of the car with the discount; d(x) = 78. Write a function c(x) that represents the price of the car with the incentive; c(x) = 79. Write a function (using function composition) that represents the price of the car if the discount is applied before the incentive; (co d)(x)= -
