The basic percent formula is P = B × R. Show how to find the formula to solve for R (rate). (See Objective.)
Use the basic percent formula to solve for rate. In this type of percent problem, the part and base are given, and the rate must be found. The formula for rate is found from the formula P = B × R. To find the rate using the diagram, cover R to get
or part ÷ base.
Actually, the formula P = B × R can be used to find either P, B, or R as long as the values of two of the three components are known.
