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
The calculation is correct up until the last step. To find out how many ounces of coffee she is allowed daily, you need to multiply the total ounces of coffee (40) by the percentage she is allowed (25%).
40 ounces * 0.25 = 10 ounces
So, if she follows the physician's instructions, she is allowed 10 ounces of coffee daily.
