A short-order cook can prepare 40 hamburgers in 30 minutes. The cook calculates a unit rate of 60 hamburgers per hour. She multi
plies 60 by 3 to estimate that she can prepare 180 hamburgers in 3 hours. Which statement describes the accuracy of the cook’s estimate? a.)The estimate is correct. b.)The estimate is incorrect because the cook can prepare 40 hamburgers per hour, not 60. The estimate is incorrect because the cook can prepare 80 hamburgers per hour, not 60. c.)The estimate is incorrect because the 180 hamburgers needs to be divided by 1/2 hours. d.)The estimate is incorrect because the 60 hamburgers per hour should have been divided by 3 hours.
Well if you divide 25.6 by 8 and then multiply four by that answer then you have the answer for a, so 4 times 3.2=12.8 , and then you would multiply 25.6 and 12.8 which is 327.68
