: 2.猴哥數學46題
: A certain doctor suggests that an individual's daily water intake be 1/2 ounce
: per pound of body weight plus 8 ounce for every 25 pounds by which the
: individual exceeds his or her idea weight. If the doctor suggested a daily
: water intake of 136 ounces for a particular 240-pound individual, how many
: pounds above his or her idea weight is that individual?
設 idea weight = x
136 = (240/2) + [(240-x)/25]*8
16 = [(240-x)/25]*8
2 = (240-x)/25
50 = 240 - x
不正好是 50 ^^?
: 答案是50 但是由答案回推感覺是錯的 感覺題目有問題....算不出答案...
