To calculate this, we have to establish a proportion :
If 1 gallon of milk is drunk in 3 days,
X gallons will be drunk in 5 days
X gallons = 1 gallon*5days/3days = 1.66 gallons will drink in 5 days.
We can round to the first decimal place 1.66 ≈ 1.7 gallons approximately.
Answer : 1.7 gallons will Brian family drink in five days, approximately.
Hope this helps!

Step-by-step explanation:
the over all total equals 200 and you can not subtract the 2 variables to get the total you have to add them
8745, 8475, 7485, 7845, 4857, 4785, 8547, 8457, 5487, 5847, 4597, 4857
7548, 7458, 5478, 5784, 4578, 4758, 8758, 8578, 5784, 5874, 7584, 7854
The frequency table is attached.
Since there were 30 people out of the 60 that received cold medicine, that means that 60-30=30 people did not.
Since 26 people had a cold longer than 7 days, this means 60-26=34 had a cold that was less than or equal to 7 days.
14 people had a cold longer than 7 days and received medicine; this means that 26-14=12 people had a cold longer than 7 days and did not receive medicine.
30-14=16 people received medicine and had a cold less than or equal to 7 days.
30-12=18 people did not receive medicine and had a cold less than or equal to 7 days.
