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.

f[c(p)] = 0.784p

Step-by-step explanation:

sales discount = 30%

sales tax = 12%

c(p) = 0.7p where p is the original price

f(c) = 1.12c where c is the sales price of the bike.

f[c(p)] = 1.12(0.7p)

f[c(p)] = 0.784p    Last option.

Assume: p = 100

c(100) = 0.7(100) = 70

f(70) = 1.12(70) = 78.4

f[70(100)] = 0.784(100) = 78.4

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.
