$0.3 per lb per year.

Step-by-step explanation:

We know that the rate of change in price is given by :-

$r=\frac{\text{Change in price}}{\text{Time}}$

Given: The price of apples went from $1.99 per lb to $3.19 per lb in four years.

Change in price = $\$3.19-\$1.99=\$1.2$

Time = 4 years

Now, the rate of change of the price of apples is given by :-

$r=\frac{1.2}{4}=0.3$

Hence, the rate of change of the price of apples= $0.3 per lb per year.

Answer from: Quest

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function $y=f(x)$ the average rate of change from point $a(a,f(a))$ to point $b(b,f(b))$ can be calculated as

$\text{average rate of change}=\dfrac{f(b)-f(a)}{b-a}.$

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

$\text{average rate of change}=\dfrac{2-8}{10-2}=\dfrac{-6}{8}=-\dfrac{3}{4}.$

The graph below shows the number of houses sold over x days. what is the average rate of change from
