Mr. Green sold 50 candy bars in a week when he priced each at $2. From his experience, he knows that if he sells each candy bar for $1.50, he will sell 10 more candy bars per week. A. Write an equation for the number of candy bars, c sold each week in terms of the price, p. B. Using your equation, determine what price will result in zero candy bars per week being sold? C. Determine if Mr. Green wants to sell at least 75 candy bars each week, what is the range of possible prices for the windsocks? Use your equation from part a to help you write an inequality, and solve algebraically.
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
