Adrian's computer cost 20% less than Jocelyn's computer. Adrian's computer cost $640. Adrian's
computer cost 15% more than Corbin's computer.
A. Write an equation that could be used to find the cost of Jocelyn's computer.
B. Write an equation that could be used to find the cost of Corbin's
computer.

  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).

$4

step-by-step explanation:

$30×5=$150

$150 minus $130=$20

$20÷5=$4.
