HURR! Justin’s doctor said that the expression StartFraction x + y + 5 over 2 EndFraction, where x and y are his parents’ current heights in inches, gives an estimate of how tall Justin will be as an adult. Justin’s work evaluating the formula is shown below. Mom’s height = 54 inches Dad’s height = 71 inches StartFraction 71 + 54 + 5 over 2 EndFraction = 71 + 27 + 5 = 103 inches What error did Justin make? A. He should have made x equal 54 and y equal 71. B. He should have added the values in the numerator before dividing by 2. C. He should have divided the 71 by 2 instead of the 27. D. He should have made the numerator 76 + 59.
