Please help me solve the expression for “n”
1 answer:
Answer:
n = 2
Step-by-step explanation:
In order for the ratio to have a value of 1, the sum of exponents in the numerator must equal the sum of exponents in the denominator:
n + 7 = 9
n = 9 -7 . . . . . . subtract 7 from both sides of the equation
n = 2

Alternatively, you can simplify the given expression:
Hopefully, it is clear to you that the value of n must be 2 in order to make the numerator equal to the denominator.

To solve this we are going to use the simple interest formula: 
where
is the final amount.
is the initial investment.
is the interest rate in decimal form.
is the time in years.
Investment A. We know that the initial investment is $10,000, so
. We also know that the number of years is 5, so 
. To convert the interest rate to decimal form, we are going to divide the rate by 100%
Lets replace those values in our formula to find:
Investment B.
, 
, and 
.
We can conclude that investment A will be worth than investment B at the end of the investment period.
