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?
Thoughts? Step-by-step reasoning:
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.
Thus, the answer is 55.
