Leo is purchasing a bike that is on sale for 30% off. he knows the function that represents the sale price of his bike is c(p) = 0.7p, where p is the original price of the bike. he also knows he has to pay 12% sale's tax on the bike. the price of the bike with tax is f(c) = 1.12c, where c is the sale price of the bike.

determine the function that can be used to calculate the final price of leo's bike by solving for f[c(p)].

(a) f[c(p)] = 1.82cp
(b) f[c(p)] = 1.82p
(c) f[c(p)] = 0.784cp
(d)f[c(p)] = 0.784p
