Dishwashers are on sale for 25% off the original price (d), which can be expressed with the function p(d) = 0.75d. Local taxes are an additional 14% of the discounted price, which can be expressed with the function c(p) = 1.14p. Using this information, which of the following represents the final price of a dishwasher with the discount and taxes applied?

c(p) ⋅ p(d) = 0.855pd
c(p) + p(d) = 1.89d
c[p(d)] = 0.855d
d[c(p)] = 1.89p
