I think D
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.
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.
Time for two dozen cookies = 23 min
Time for 12 dozen = (6 * time for two dozen) = (6*23) = 138
How many hours is that?
Time for 12 dozen = (6 * time for two dozen) = (6*23) = 138
How many hours is that?
it's C
