What will I learn?

The Simple Interest Formulas Course provides a quick, practical way to master I = P·r·t and A = P + I, with clear units, conversions, and rounding rules. Work through guided examples, case studies, and comparisons of real offers to calculate interest, total amounts, and effective cost per dollar. Learn when simple interest is suitable, how it differs from compound interest, and how to present accurate, well-explained numeric results.
