Class I Formula list

Rate Formulas
  price + tax    =  total
  rate  X time   =  wage
  rate  X value  =  tax
  rate  X price  =  tax
  rate  X time   =  yield
  rate  X time   =  distance
  rate  X time   =  effort 
  rate  X (time1 +  time2)  =  wage
  rate1 X time1  +  rate2   X  time2 = wage
  (percent/100) X wage = deductions
  (right/total) X 100 = percent
  value per unit X number of units = value
  volume X solution percent = solvent


Sum Formulas
  price + tax = total
  right + wrong = total
  number of type one + number of type two = total number
  rate one + rate two = combined rate
  distance one + distance two = total distance
  gross wage - deductions = net wage
  true value - measured value = error
  angle one + angle two + angle three = 180 degrees
        (the sum of the interior angles of a triangle)
  angle one + angle two = 90 degrees (complementary angles)
  angle one + angle two = 180 degrees (suplementary angles)
