Dan is choosing between two exercise routines.

In routine 1, he burns 20 calories walking. He then runs at a rate that burns 10.5 calories per minute.
In routine 2, he burns 39 calories walking. He then runs at a rate that burns 5.75 calories per minute.

For what amounts of time spent running will routine 1 burn at most as many calories as routine 2? Use t for the number of minutes spent running, and solve your inequality for t.

1 answer

To solve for "as many," use this equation to solve for t.

20 + 10.5t = 39 + 5.75t
