You deposit $5000 in an account that earns 5% simple interest. How long will it take to earn $800 in interest?

3.2 years

Step-by-step explanation:

You are going to want to use the simple interest formula for this:

I = interest amount

P = principal amount

r = interest rate (decimal)

First, change 5% into a decimal:

5% -> -> 0.05

Now, lets plug the values into the equation:

It will take 3.2 years to earn $800 in interest.

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100

step-by-step explanation:

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
