Answer: Choice B) Investment decreases by 3% each month
=====================================================
Explanation:
We won't use the value 2500 at all.
The base of the exponential is 0.97
Set this equal to 1+r and solve for r
1+r = 0.97
r = 0.97-1
r = -0.03
The negative r value indicates we have exponential decay, so the value of the investment decreases by 3% each month.
Let's say you had $100 to start off. This would mean the investment would be worth $97 after one month is up.
Answer:
A. 4x-10
Step-by-step explanation:
We see that this is a rectangle. To find the perimeter, we do L+W+L+W. So in this case, we can do (x+2)+(x-7)+(x+2)+(x-7). We can also simplify this to 2(x+2)+2(x-7)
Combine like terms now.
Simplify this to:
2x+4+2x-14
Simplify further:
4x-10
4.4=-2.

Answer:
x = 60 cents.
Step-by-step explanation:
The man wants to make up 100 one-pound jars of nuts, it means he will need 100 pounds of nuts. He plans to use 40 pounds of one type of nuts, so he needs 60 pounds of the other type of nuts to get 100 pounds.
Now, with this we can write a linear equation:
(40*0.75)+(60*x) = 100*0.66 (1)
Where:
- 0.75 is the unit price of the 40 pounds of one type of nuts.
- x is the unit price of the 60 pounds of the other type of nuts.
- 0.66 is the unit price of 100 one-pound jars.
Let's solve the equation (1) for x:
Therefore, x = 60 cents.
I hope it helps you!
