A pharmacy mixes different concentrations of saline solutions for its customers. The pharmacy has a supply of two concentrations, 0.5% and 5%. The function y=(100)(0.05)+x(0.005)/100+x gives the concentration of the saline solution after adding x milliliters of the 0.5% solution to 100 milliliters of the 5% solution. How many milliliters of the 0.5% solution must be added to the 5% solution to get a 0.95% solution?
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.
