Determine the amount of an investment if $250 is invested at an interest rate of 10.3% for 40 years. round to the rearest penny

Final answer is $1280.

Step-by-step explanation:

Given that $250 is invested at an interest rate of 10.3% for 40 years.

Now we need to determine the amount of that investment after 40 years.

It doesn't say anything about compounding period so I will consider that as simple interest.

Hence let's use simple interest formula:

Where amount invested = P = 250

rate of interest = R = 10.3% = 0.103

Time = T = 40 years

Now plug these values into above formula

Hence final answer is $1280.

$1280.

Step-by-step explanation:

We have been given that an amount of $250 is invested at an interest rate of 10.3% for 40 years.

To find the amount after 40 years, we will use simple interest formula.

, where,

A = Amount after t years,

P = Principal amount,

r = Annual interest rate in decimal form,

t = Time in years.

Let us convert our given interest rate in decimal as:

Upon substituting our given values in above formula, we will get:

Therefore, there will be $1280 in account after 40 years.

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
