Answer: $0.3 per lb per year.
Step-by-step explanation:
We know that the rate of change in price is given by :-
Given: The price of apples went from $1.99 per lb to $3.19 per lb in four years.
Change in price =
Time = 4 years
Now, the rate of change of the price of apples is given by :-
Hence, the rate of change of the price of apples= $0.3 per lb per year.
Answer:
$0.30 per lb per year

Answer:
Step-by-step explanation:
We are asked to write 77.7% as a decimal.
We know that percent means per hundred.
To write 77.7% as decimal, we will divide 77.7 by 100 as:
Move decimal to left by two digits.
Let us set 0.777 equal to x as:
We can see that our decimal has three 7 digits after decimal, therefore, 1 digit is repeating after decimal.
The constant of variation is 10/3.
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 = 9 is an equation.
We have,
y ∝ x
This can be written as an equation as,
y = kx
Where k is the constant of variation.
Now,
When x = 3, y = 10.
10 = 3k
k = 10/3
Thus,
The value of k is 10/3.
