Answer 1

Answer:

a) 31.25

b) 30

Step-by-step explanation:

The price function is given as:

$\mathbf{P(x) =\left \{ {1.25x \ for \ x \ \leq \ 25} \atop {1.20x \ for \ x \ > \ 25}} \right. }$

Find:

$\mathbf{ \lim_{x \to 25^-} P_{(x)}}$

$\mathbf{ \lim_{x \to 25^+} P_{(x)}}$

$\mathbf{P(x) =\left \{ {1.25x \ for \ x \ \leq \ 25} \atop {1.20x \ for \ x \ > \ 25}} \right. }$

$\mathbf{ \lim_{x \to 25^-} P_{(x)} = 1.25 * 25} \\ \\ =31.25$

$\mathbf{ \lim_{x \to 25^+} P_{(x)} = 1.20 * 25} \\ \\ =30$
