Sam deposits $1,000 into an account that pays 6% simple interest annually. He plans to take the money out after 3.5 years. What
lara31 [8.8K]
Well, the formula for simple interest is 

I=prt

"I" is interest, "p" is the principal, "r" is the rate, and "t" is the time.

If you substitute the numbers, you get

I=1,000(0.06)(3.5)

When you multiply them together, you get 

I=210

So, the simple interest for 3.5 years is $210.

But, in order to get the total balance, you have to add the interest and the principal together.

B=1000+210 \\ B=1210

So, the balance after 3.5 years is $1,210.
