How would that affect his rate of change? Would Sam pay more or less than Carmen Carmen buys a new bicycle. Her weekly payment plan is shown in the table. Sam also buys a new bicycle. His weekly payment plan is shown in the graph. Find The amount Carmen owes decreases by $50 each week, so her rate of change The amount Sam owes decreases by $25 each week, so his rate of change is --$25. the rate of change for each function and Graph Carmen's function on the same grid as Sam's 2 How does the graph show that the rate of change
