The physician tells a woman who usually drinks 5 cup of coffee daily to cut down her consumption by 75%. If this complaint with physician's instructions, how many ounces of coffee is she allowed daily? I got 3.75. The answer is 10. It's asking for ounces so you have to convert cups to ounces first. 5 cups times 8 ounces is 40 ounces. She's allowed 25%, so 40 ounces times .25=
a) 7.5
b) 10
c) 15
d) 30
