document.write( "Question 927141: Coffee is best enjoyed at a temperature of 121° F. A restaurant owner wants to discover the temperature T at which he should serve his coffee so that it will have cooled to this ideal temperature in 6 minutes. He discovers that a cup of coffee served at 198° F cools to 185° F in one minute when his restaurant is at 70° F. If he maintains the restaurant temperature at 70° F, at what temperature should he serve the coffee to meet his goal? \n" ); document.write( "

The rate of cooling is: $\"+198+-+185+=+13+\"$ degrees F/min
\n" ); document.write( " $\"+T+-13%2A6+=+121+\"$
\n" ); document.write( " $\"+T+=+121+%2B+78+\"$
\n" ); document.write( " $\"+T+=+199+\"$ degrees F
