Q. t=14p+2 t=\frac{1}{4} p+2 \newlineAna uses the given equation to determine the number of hours, t t , to roast a p p -pound turkey. How many more minutes would it take Ana to roast a 1313 -pound turkey than a 1212 -pound turkey?\newlineChoose 11 answer:\newline(A) 22 minutes\newline(B) 44 minutes\newline(C) 1515 minutes\newline(D) 6060 minutes
  1. Plug in p=12p=12: First, plug in p=12p=12 into the equation to find the time for a 1212-pound turkey. t=(14)12+2t=(\frac{1}{4})\cdot12+2.
  2. Calculate time for 1212-pound turkey: Calculate the time for a 1212-pound turkey. (1/4)×12=3(1/4)\times 12=3, so t=3+2=5t=3+2=5 hours.
  3. Plug in p=13p=13: Now, plug in p=13p=13 into the equation to find the time for a 1313-pound turkey. t=1413+2t=\frac{1}{4}\cdot13+2.
  4. Calculate time for 1313-pound turkey: Calculate the time for a 1313-pound turkey. (14)×13=3.25(\frac{1}{4})\times 13=3.25, so t=3.25+2=5.25t=3.25+2=5.25 hours.
  5. Find time difference: Find the difference in time between roasting a 1313-pound and a 1212-pound turkey. 5.255.25 hours - 55 hours = 0.250.25 hours.
  6. Convert to minutes: Convert the difference in hours to minutes. 0.250.25 hours ×60\times 60 minutes/hour =15= 15 minutes.
