Question

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?
a. c ( p ) ⋅ p ( d ) = 0.855pd
b. c ( p ) + p ( d ) = 1.89d
c. c [ p ( d ) ] = 0.855d
d. d [ c ( p ) ] = 1.89p

Answer 1

Price of the dishwashers on sale are represented with the function: p ( d ) = 0.75 d ( 100 % - 25 % = 75 % or 0.75 d ): After that we have additional 14 % on the discounted price ( 100 % + 14 % = 114 % OR 1.14 ): C ( P ) = 1.14 P. Finally, c ( p ( d ) ) = 1.14 * 0.75 d = 0.855 d. Answer: C ) c [ p ( d ) ] = 0.855 d Hope I helped! :) Cheers!
