Question

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)].
f[c(p)] = 1.82cp
f[c(p)] = 1.82p
f[c(p)] = 0.784cp
f[c(p)] = 0.784p

Answer 1

F[c(p)] = (1.12)(0.7p) = 0.784p

A single function should have a single variable.

Answer 2

Answer: The answer would be f[c(p)] = (1.12)(0.7p) = 0.784p

Step-by-step explanation:

A single function should have a single variable.
