(4) Proportionality. The student applies mathematical process standards to represent and solve problems involving proportional relationships. The student is expected to:

• (A) represent constant rates of change in mathematical and real-world problems given pictorial, tabular, verbal, numeric, graphical, and algebraic representations, including d = rt;

• (B) calculate unit rates from rates in mathematical and real-world problems;

• (C) determine the constant of proportionality (k = y/x) within mathematical and real-world problems;

• (D) solve problems involving ratios, rates, and percents, including multi-step problems involving percent increase and percent decrease, and financial literacy problems; and

• (E) convert between measurement systems, including the use of proportions and the use of unit rates.
