At a local fruit stand, pia spends $7.92 for 4 pounds of blackberries. how much can she expect to pay for 8 pounds of blackberries? at a local fruit stand, pia spends $7.92 for 4 pounds of blackberries. how much can she expect to pay for 8 pounds of blackberries?

$7.92 / 4 lbs   = x /8 lbs

multiply top and bottom by 2

15.84/8 lbs

it will cost $15.84  for 8 lbs

took the test it's 94

  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).
