Ahmad is choosing between two exercise routines.

In Routine #1, he burns 50 calories walking. He then runs at a rate that burns 12.9

calories per minute. For what amounts of time spent running will Routine #1 burn fewer calories than Routine #2?

Use t for the number of minutes spent running, and solve your inequality for t
