A 4-pound bag of sugar costs $16.64. What is the price per ounce?

$.26

Step-by-step explanation:

Convert pounds to ounces:

Pounds : Ounces

1 : 16

4 : ?

(multiply by 4)

4 : 64

Therefore, a 64 oz bag of sugar costs $16.64

Set up a ratio:

Ounces : Price

64 : 16.64

Find the unit rate:

64 : 16.64

(divide both sides by 64)

1 : .26

Therefore, it costs 26 cents per ounce.

  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).
