Answer:
Supermarkets are often cited as among the types of businesses with the lowest profit margins. It's true. Grocery store profit margins typically range from 1 percent to 3 percent, depending on the items. Grocery stores make their money on volume. They may not make much on any one item, but it's the rare shopper who only buys one item. That's why the store kindly provides big shopping carts for their customers. With not much additional effort, the grocery store sells you 20 items or more, making much more profit than they would have if you had bought only one item.Explanation:

Consider the curve defined by x^2=e^x-y for x>0. At what value of x does the curve have a horizontal tangent?​
The curve [tex]x^{2} = e^{x-y}[/tex] for [tex]x > 0[/tex] has a horizontal tangent for [tex]x = 2[/tex].
In this question we must use implicit differentiation to determine the value of [tex]x[/tex] associated with a given slope. By differential calculus we know that a curve of the form [tex]y = f(x)[/tex] has a horizontal tangent if and only if [tex]\frac{dy}{dx} = 0[/tex]. Now we derive an expression for the first derivative:
[tex]2\cdot x = e^{x-y}\cdot \left(1-\frac{dy}{dx} \right)[/tex]
[tex]1 - \frac{dy}{dx} = \frac{2\cdot x}{e^{x-y}}[/tex]
[tex]\frac{dy}{dx} = 1 - \frac{2\cdot x}{e^{x-y}}[/tex]
[tex]\frac{dy}{dx} = 1 - \frac{2\cdot x}{x^{2}}[/tex]
[tex]\frac{dy}{dx} = 1 - \frac{2}{x}[/tex] (1)
If we know that [tex]\frac{dy}{dx} = 0[/tex], then the value of [tex]x[/tex] so that the curve have a horizontal tangent is:
[tex]1-\frac{2}{x} = 0[/tex]
[tex]\frac{2}{x} = 1[/tex]
[tex]x = 2[/tex]
The curve [tex]x^{2} = e^{x-y}[/tex] for [tex]x > 0[/tex] has a horizontal tangent for [tex]x = 2[/tex].
