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?

Respuesta :

Using proportions, it is found that the expression that represents the final price is given as follows:

C(t) = 0.918t.

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, we have that:

  • With the discount, the price is of 0.85t.
  • With the taxes, the price is increased by 8%, hence multiplied by 1.08.

Thus the expression for the final cost is:

C(t) = t x 0.85 x 1.08 = 0.918t.
