Tell you what. I'll build the inequality, and you solve it ...
18 + 10.25t > 12.5t
David is choosing between two exercise routines.
In Routine #1, he burns 18 calories walking. He then runs at a rate that burns 10.25 calories per minute.
In Routine #2, he does only running, burning 12.5 calories per minute.
For what amounts of time spent running will Routine #1 burn more calories than Routine #2?
Use t for the number of minutes spent running, and solve your inequality for t.
