Lenny and Thad spend a certain amount of money from their money box each month to buy comic books. The table shows the relationship between the amount of money (y) remaining in Lenny's money box and the number of months (x): Function 1 Number of Months (x) Amount Remaining (in $) (y) 1 75 2 60 3 45 4 30 The equation shows the relationship between the amount of money (y) remaining in Thad’s money box and the number of months (x): Function 2: y = −12x + 80 Which statement explains which function shows a greater rate of change?

A) Function 2 shows a greater rate of change, because Lenny spends $15 each month and Thad spends $12 each month. B) Function 2 shows a greater rate of change, because Lenny spends $75 each month and Thad spends $12 each month. Function 1 shows a greater rate of change, because Lenny spends $15 each month and C) Thad spends $12 each month. Function 1 shows a greater rate of change, because Lenny spends $15 each month and D)Thad spends $80 each month.

Or you can just solve the 2nd equation for 1,2,3,4,5 etc

Hmm...Lets take function two: y = −12x + 80 Solve y for x = 1.

  • anonymous

Well ,first I divided 12 by both sides, 12/12 which cancels out, and 12/80 Then I got 6.6 repeated... Am I doing this right?
undeadknight26
  • undeadknight26
Hmm...
undeadknight26
  • undeadknight26
It's 68 I believe...

  • undeadknight26
The change of rate: Function 1: 15 Function 2: 12.
