数学题怎么都读不懂==
以下这道题就是读不懂了.
For food products to be labeled"light," the U.S.Food and Drug Administration requires that the altered product must either contain one-third or fewer calories than the regular product or it must contain one-half or less fat than the regular product.If a serving of Miracle Whip?Light contains 20 calories and 1.5 grams of fat,then what must be true about either the number of calories or the grams of fat in a serving of regular Miracle Whip?

Answer 1

就是说,FDA 有规定,凡是标"light" 的食品,要么卡路里含量必须 小于等于常规食品卡路里的1/3,要么脂肪含量必须小于等于常规食品脂肪的一半
现在 Miracle Whip Light 这种色拉酱含 20 卡路里,1.5克脂肪
让你求常规 Miracle Whip 的卡路里或者脂肪含量 要满足的条件
你是没看懂题,计算我就不帮你算了,呵呵~~
