Hi there!
In order to answer your question you’ll need to write an equation in which “X” would be the number of containers you need to sell :
4X - 28 = 20
This equation means that each container you sell gives you $4, you also need to subtract $28 because that’s the cost for making the cookies and the equation is equal to 20 because you want to make a $20 profit.
Now that your equation in written down, you can solve it by isolating “X” :
4X - 28 = 20
Add 28 on each side of the equation → 20 + 28 = 48
4X = 48
Divide each side of the equation by 4 → 48 ÷ 4 = 12
X = 12
Your answer is D): In order to earn a $20 profit, you need to sell 12 containers.
There you go! I really hope this helped, if there’s anything just let me know! ☻
Answer:
The correct answer is C) $112.50.
Step-by-step explanation:
The problem requires us to calculate future weekly bill that melinda miller will pay after 3 years if inflation rates is 4%. This can easily be calculated using compound factor formula.
Future value = Present value (1+I%)^n
Future value = 100 (1+4%)^3
Future value = 112.5 dollars
The extreme value is −4. To see whether it is a maximum or aminimum, in this case we can simply look at the graph. f(x) is a parabola, and we can see that the turning point is a minimum. By finding the value of x where the derivative is 0, then, we have discovered that the vertex of the parabola is at (3, −4).
