erson buys a phone for $81 and signs up for a single-line phone plan with 2000 monthly anytime minutes. The plan costs $119.92 per month. Write an equation that can be used to determine the total cost, C(t), of this phone plan for t months. Then, find the cost for 23 months, assuming that the number of minutes the person uses does not exceed 2000 per month.
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.
