Question

Tablets 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?

c[p(t)] = 0.918t
c(p) + p(t) = 1.93t
c(p) ⋅ p(t) = 0.918pt
t[c(p)] = 1.93p

Answer 1

the final price is tax added to the discount price, so

c(p(t)) = 1.06*0.85t = 0.918t

Read the text carefully. They actually gave the formula to you : c(p)
