B) between 3 and 4 hours
C) between 2 and 3 hours
D) between 1 and 2 hours
it's C
lol i hope i don't get this wrong
To find a reasonable estimate of the amount of time it will take Brandon to make 12 dozen cookies, we can use ratios and proportions.
First, we need to determine the number of minutes it takes to make 1 dozen cookies. Since Brandon can make 2 dozen cookies in 23 minutes, we can divide 23 minutes by 2 dozen to find the time it takes to make 1 dozen cookies.
23 minutes ÷ 2 dozen = 11.5 minutes per dozen
Next, we can use this information to find out how long it will take him to make 12 dozen cookies.
11.5 minutes per dozen x 12 dozen = 138 minutes
So, it will take him 138 minutes to make 12 dozen cookies.
Now, we can estimate this time in terms of hours. There are 60 minutes in an hour, so we divide 138 minutes by 60 to find the number of hours.
138 minutes ÷ 60 = 2.3 hours
Since the question asks for a reasonable estimate, we can round the decimal value.
Therefore, a reasonable estimate for the amount of time it will take Brandon to make 12 dozen cookies is between 2 and 3 hours.
Answer: C) between 2 and 3 hours
I don't understand
Time for two dozen cookies = 23 min
Time for 12 dozen = (6 * time for two dozen) = (6*23) = 138
How many hours is that?
amount=rate*time
12doz=(2doz/(23/60)hr)*time
12=(2*60/23)*time
12=(120/23)*time
time= 12*23/120 hrs So your thinking is off. Do the math.
