Question

A slice of pizza costs $4.00. Based on Ashley’s demand curve in Figure 4.4, what is her quantity demanded of pizza at this price?
A. one


B. five


C. two


D. zero

Answer 1

Answer:

Option D. zero

Explanation:

see the attached figure to better understand the problem

Let

x -----> the demand of slices of pizza for day

y ----> the price per slice

Looking at the figure

The domain of Ashley’s demand curve is the interval [0,1,2,3,4,5]

The range of Ashley’s demand curve  is the interval [0.5,1.0,1.5,2.0,2.5,3.0]

If a slice of pizza  costs $4.00

then

based on Ashley’s demand curve

The amount of pizza demanded at this price is zero, because the value of y=$4 is not in the range of Ashley's demand curve.
