Answer:
<em>The car will worth $15815 after 5 years.</em>
Step-by-step explanation:
The formula is: , where P = Initial cost, A = Final cost, r = Rate of change in cost per year and t = Number of years.
Here,
and
As here the <u>value of the car depreciates every year, so we need to plug the value of as negative</u>. So,
Now plugging the above values into the formula, we will get.....
<em>(Rounded to the nearest dollar)</em>
So, the car will worth $15815 after 5 years.
Hot Dog Stand
Let
C--------> total cost of the hot dog
x-------> is the number of toppings
we know that
where
The slope of the linear equation is equal to
The y-coordinate of the y-intercept of the linear function is equal to
That means -------> This is the cost of the hot dog without topping
Hamburgers Stand
Let
C--------> total cost of the hamburger
x-------> is the number of toppings
we know that
where
The slope of the linear equation is equal to
The y-coordinate of the y-intercept of the linear function is equal to
That means -------> This is the cost of the hamburger without topping
therefore
<u>the answer is</u>
The linear equation of the hamburger cost is equal to
