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.
I think the answer would be B. 4 cm
To solve this equation, you will need to set up a proportion where you set two fractions equal to each other.
Let x = the unknown amount of milk

You would then crossmultiply and solve for x.
8x = 400(6)
8x = 2400
x = 2400/8
x = 300
You will need 300 mL of milk to make 6 pancakes if you previously needed 400 mL to make 8 pancakes.
it is b because it is multiplying by 2s.
