Let x represent the number of envelopes stuffed. A) express the cost C as a function of x B) express the revenue R as a function of x C) determine analytically the value of x for which revenue equals cost
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.
Students stuff envelopes for extra money. Their initial cost to obtain the information for the job $260. Each envelope costs $0.03 and they get paid $0.05 per envelope stuffed.
