[計量] 請教兩題計量
Q1. A1,Lew, and Karen pooled their funds to buy a gift
for friend. A1 contributed $2 less than 1/3 of the
cost of the gift and Lew contributed $2 more than
1/4 of the cost. If Karen contributed the remaining
$15, what was the cost of the gift?
Ans：36 (可是我一直算22.5...)
Q2. Four cups of milk are to be poured into a 2-cup
bottle and a 4-cup bottle. If each bottle is to
be filled to the same fraction of its capacity,
how many cups of milk should be poured into the
4-cup bottle?
Ans：8/3

可能是我不了解題意吧，懇請各位幫忙解答，謝謝
