Question 1154573: A roast chicken recipe calls for pre-roasting the chicken for a certain amount of time at a high temperature first, then reducing the temperature and roasting for an additional 18 minutes per pound.
Austin's 4.3 pound chicken took 88.4 minutes to roast.
How many minutes would it take to cook a chicken that was double in weight as Austin's chicken?

You can put this solution on YOUR website!
Let +t+ = time in minutes to pre-roast chicken
+t+%2B+18%2A4.3+=+88.4+
+t+%2B+77.4+=+88.4+
+t+=+11+ min
-----------------------
Let +T+ = time in minutes to cook chicken
+2%2A4.3+=+8.6+ pounds
+t+%2B+18%2A8.6+=+T+
+11+%2B+154.8+=+T+
+T+=+165.8+ minutes
-----------------------------
