Answer: 10,000(1.03)⁴ˣ
<u>Step-by-step explanation:</u>
A = P(1 + 
)ⁿˣ
A is the amount (new balance): <u> unknown </u>
P is the principal (amount you started with): <u> 10,000 </u>
r is the interest rate: 12% = <u> .12 </u>
n is the number of times per year it is compounded: quarterly = <u> 4 </u>
x is the number of years: <u> x </u>
A = 10,000(1 + 
)⁴ˣ
= 10,000(1 + .03)⁴ˣ
= 10,000(1.03)⁴ˣ
-9(4+x)>-126
-36-9x>-126
-36+36-9x>-126+36
-9x>-90
-9x/-9<-90/-9
x<10
Answer:
<u>After a 75% increase, it would become</u>
x + 75%x = x + 0.75x = x(1 + 0.75) = 1.75x
<u>After a 50% decrease, it would become</u>
1.75x - 50%(1.75x) = 1.75x - 0.5(1.75x) = 1.75x - 0.875x = 0.875x = 
Because is less than x, the new amount would be less than the original.
As I look into the problem with a deeper meaning then math I realize this answer can be not as hard as it appears and it could be hard to answer it
Sure. what is it that you have to do with statistics
