Bella pays 7 payments of $5 each to a game store. she returns one game and receives $20 back. what is the change to the amount of money she has
?

15

Step-by-step explanation:

7(5)=35 is how much her 7 payments equal

35-20=15 is the money she has after the return

69

step-by-step explanation:

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).
