An investment of 11,000 is made into an account that earns 4.25% annual compound interest for 30 months. Assuming no other depos
LenKa [72]

Answer:

It should be $12168.75

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 4.25%/100 = 0.0425 per year,

then, solving our equation

I = 11000 × 0.0425 × 2.5 = 1168.75

I = $ 1,168.75

The simple interest accumulated

on a principal of $ 11,000.00

at a rate of 4.25% per year

for 2.5 years is $ 1,168.75.

1,168.75 + 11000 = 12168.75

Which of these inequalities means that<br> 18 is greater than three times a number?
AnnyKZ [126]
<h3>hello!</h3>

Let's write this verbal phrase as an inequality.

First of all, let the number be n.

"three times n" can be written like so:-

\pmb{3n}

Now, 18 is greater than 3n:-

\pmb{18 > 3n}

Which means 3n is less than 18:-

\bigstar{\boxed{\pmb{3n < 18}}}

<h3>note:-</h3>

Hope everything is clear; if you need any explanation/clarification, kindly let me know, and I'll comment and/or edit my answer :)
