Answer:
The expression of the ellipse is: 
Step-by-step explanation:
The equation of a ellipse can be written by the following expression:

Where 2a is the length of the major axis and 2b is the length of the minor axi. Since we were given the length of the minor vertex, then:

The length of the major axis is the distance between the two vertices.
![2a = \sqrt{[2 - (-2)]^2}\\2a = \sqrt{(2 + 2)^2}\\2a = \sqrt{4^2}\\2a = 4\\a = 2](https://tex.z-dn.net/?f=2a%20%3D%20%5Csqrt%7B%5B2%20-%20%28-2%29%5D%5E2%7D%5C%5C2a%20%3D%20%5Csqrt%7B%282%20%2B%202%29%5E2%7D%5C%5C2a%20%3D%20%5Csqrt%7B4%5E2%7D%5C%5C2a%20%3D%204%5C%5Ca%20%3D%202)
Therefore the expression of the ellipse is:

If we know that 1 lb of peaches is 0.80 cents
0.5 lb (half a pound) will be half the price
0.5lb peaches= 0.80/2=0.40 cents
