Best ResponseYou've already chosen the best response.0Tablets are on sale for 15% off the original price (t), which can be expressed with the function p(t) = 0.85t. Local taxes are an additional 8% of the discounted price (p), which can be expressed with the function c(p) = 1.08p. Using this information, which of the following represents the final price of a tablet with the discount and taxes applied based on its original price?

Best ResponseYou've already chosen the best response.0okay this is super easy you got this since (g(6)) is in parentheses, you solve that first plug in 6 for x in the function g(x) g(x) = 6  8
