Calculate the ending balance of $34,100 invested at 4% Simple Interest for 3 years.

Question 1 options:

$38,192

$30,008

$4,092

$409,200

Work Shown:

The simple interest formula is

i = P*r*t

In this case,

P = 34,100 is the amount invested (aka principal)

r = 0.04 represents the interest rate in decimal form

t = 3 is the number of years

So,

i = P*r*t

i = 34100*0.04*3

i = 4092

15-6+7=16. The expression should be written as 15-(6+7).

Step-by-step explanation:

The sum of 6 and 7 is (6+7). 15 minus the sum of 6 and 7 would then be written as 15-(6+7), because this way you subtract the entire sum from 15. The expression 15-6+7 just subtracts 6 from 15, then adds 7 onto this number, which is not the same thing as subtracting 6+7 from 15.
