After a hurricane, repair to roof will cost $2900 for materials and $50/hr in labor. a) Write a model that represents the cost of the repair C (in $) in terms of the number of hours of labor x. b) If an estimate for a new roof is $3950, after how many hours of labor would the cost to repair the roof equal the cost of a new roof?
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.
