Problema Solution
The Subweight shop aims for an absolute error of ten calories in its sandwiches. Sliced beef used in sandwiches contains 1.2 calories per gram. The weight of beef in the Subweight beef sandwich should be 225 grams. What is the accepted range of weight for beef in this sandwich?
Answer provided by our tutors
the numbers of calories that should be in the sandwich:
225 * 1.2 = 270
therefore, the acceptable calorie range for each sandwich would be:
(270-10), (270+10) = (260, 280)
converting the calorie range to weight:
(260/1.2), (280/1.2) = (216.7, 233.3)
the accepted range of weight for beef in this sandwich is approximately (216.7, 233.3) grams
