conversations.value: Can you guide me through solving this problem: Dave weighs 175 pounds and can bench press three times his body weight.  Craig can only bench press 20% of the amount Dave can.  Mark is new and can bench press 50 pounds less than Craig.  How much can Mark bench press?

conversations.value: Dave weighs 175 pounds and can bench press three times his body weight, so he can bench press 175*3 = 525 pounds
  Craig can only bench press 20% of Dave's 525 pounds, so Craig can bench press .20*525 = 105 pounds
  Craig bench presses 105 pounds and Mark does 50 pounds less than Craig, so Mark can only press 105-50 = 55 pounds
