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% sales 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. C[f(c)] = 0. 784c f[c(p)] = 1. 82p c[f(c)] = 1. 82c f[c(p)] = 0. 784p.
