# Given p(n) = 0.25n+5.2 represents the price (P) in dollars for n grams of vitamins; what would the inverse function of P represent?

Apr 28, 2018

$n \left(p\right) = 4 p - 20.8$

represents the number of grams of vitamins that you could purchase with p dollars.

#### Explanation:

The inverse function would be

$n \left(p\right) = \frac{p - 5.2}{0.25} = 4 p - 20.8$

This represents the number of grams of vitamins that you could purchase with p dollars.
