1 Glycerin, an ingredient in some toothpastes, can interfere with strengthening your teeth. 2  Glycerin layers your tooth in a sticky film that keeps the minerals in your saliva from interacting with your enamel to strengthen it.. Chew sugar-free gum. The gum promotes saliva production, without the sugar that makes weakened enamel worse. Gum with the natural sweetener xylitol doesn't feed the bacteria that weakens your enamel, and xylitol has actually been shown to strengthen tooth enamel.
Demand functions for a straight-line demand curve take the following form: Quantity = a - (b x Price). where a and b are constants that must be determined for each particular demand curve. When price changes, the result is a change in quantity demanded as one moves along the demand curve.
The market demand curve for good X includes the quantities of good X demanded by all participants in the market for good X. The market demand curve is found by taking the horizontal summation of all individual demand curves. For example, suppose that there were just two consumers in the market for good X, Consumer 1 and Consumer 2. These two consumers have different individual demand curves corresponding to their different preferences for good X. The two individual demand curves are depicted in Figure , along with the market demand curve for good X. The market demand curve for good X is found by summing together the quantities that both consumers demand at each price. For example, at a price of $1, Consumer 1 demands 2 units while Consumer 2 demands 1 unit; so, the market demand is 2 + 1 = 3 units of good X.
