Neil invested £8000 in a savings account for 2 years. He earned £640 simple interest over the two years.What was the interest rate?

Answers

Answer 1

Answer:

Final answer:

The interest rate is 4%.

Explanation:

To find the interest rate, we can use the formula:

Interest = Principal × Rate × Time

In this case, the principal is £8000, the interest is £640, and the time is 2 years. Plugging these values into the formula, we get:

£640 = £8000 × Rate × 2

Dividing both sides of the equation by £16000 gives:

Rate = £640 ÷ £16000 = 0.04

Therefore, the interest rate is 0.04 or 4%.

Can someone please help me?

Answers

Hello,

$u_(1) =2\n u_(2) =2+6\n u_(3) =2+2*6\n u_(4) =2+3*6\n...\n u_(n) =2+(n-1)**6\n u_(30) =2+29*6=176\n$

Answer B

So first u have to find the nth term, here the nth term is : 6n-4
Then replace the n with term that u want so:
6(30) - 4
= 180-4
=176
So it's B
