The table shows the relationship between the amount of money (y) remaining in Morgan's money box and the number of months (x): Function 1 Number of Months (x) Amount Remaining (in dollars) (y) 1 50 2 40 3 30 4 20 The equation shows the relationship between the amount of money (y) remaining in Leigh's money box and the number of months (x): Function 2: y = −9x + 60 Which statement explains which function shows a greater rate of change?

Answer 1

The first one since after each x interval the y is decreasing by 10 and in the second equation after each x interval the y is decreasing by 9

The first representation is the answer: Morgan
