A local bank in town offers two types of savings plan with different interest rates to customers. Plan A offers an annual intere
scoray [572]
Assuming he had not dealt with the bank offering plan B before, he has nothing deposited two years back.  Hence plan B only gives him only 0.2% annual interest for his deposit.
Plan A gives 0.25% for his deposit all the time.
So plan A is more advantageous.

For durations, 
To reach $1,000,000 from $100,000, the money needs to grow 10 fold, or
(1+i)^n=10
n=log(10)/log(1+i).

So for plan A:
n=log(10)/log(1.0025)=922.18 years, while for

plan B
n=log(10)/log(1.0020)=1152.44 years.
 
Hope the bank(s) still exist at that time.

Isn’t it just 5? Why would it say check all that apply
LenKa [72]

Answer: 25^\frac{1}{2}

Step-by-step explanation:

25 = 5*5 or -5 * -5

yes, that is correct. However, you forgot another property of roots. Roots are simply exponential fractions.

\sqrt[n]{x^m}=x^\frac{m}{n}

Therefore, \sqrt{25} can also be rewritten as: 25^\frac{1}{2}. Notice that it cannot be -25 because that would be a negative square root which will give us an imaginary number.

A discounted amusement park ticket costs $12.95 less than the original price (p). Write and solve an equation to find the origin
Elena-2011 [213]
P = the original price of the ticket.

Let x =  the discounted price.
The discounted price IS $12.95 less than the original price. Therefore
x = p - 12.95

Add 12.95 to each side.
p = x + 12.95

Answer:
The equation is
p = x + 12.95
where
p = original price
x = discounted price
