1) Net pay for an employee is the result of applying a linear equation. For example, social security is about 8% of the adjusted gross pay. While health insurance might be $500. So we would have:
.
Net Pay = Gross Pay - .08*Gross Pay - 500
.
2) A cell phone plan might be $30 per month plus 25 cents per text message. So the monthly bill would be:
.
cost = .25*number of messages + 30, which is the classic y = mx + b equation.
