conversations.value: They made $10 because 2 x 5 = 10
  They made $1 off single pieces because 100 x .01 = 1
  They made $.9 off double pieces because 45 x .02 = .9
  They made $1.5 off triple pieces because 50 x .03 = 1.5
  They earned $3.4 off the first three types because 1 + .9 + 1.5 = 3.4
  They earned $6.6 off the quadruple pieces because 10 - 3.4 = 6.6
  They sold 165 quadruple pieces because 6.6 / .04 = 165
