The problem states find the simple interest . Assume a 360 day year. Round result.

$17000 at 9% for 119 days.

So,
I know i have to use the formula

I=Prt

so my p = 17000; r = 0.09; t= ? how do iwrite out time if it has 119 days and the t needs to be in years....

time will be 119/360 years, a fraction.

You'll need to find out what part of a year 119 days are. Divide 119 by 365 and you'll get 0.326. (That tells us that 119 days is almost 1/3 of a year.)

I = 17,000 x .09 x .326

Correction -- I forgot that you said to use a 360 day year.

Your decimal should be 0.33

So, what i get for interest would be

504.90 should i leave it as is or do i round it tobe:
505 flat

Since this is money, and banks (and their customers) want to be accurate, your answer is that the interest is $504.90. The bank wouldn't be happy if you took ten cents from it. <g>

The problem is not clear on how to round, to what place. Normally, dealing with interest, you round to the nearest cent. That is what the Bank does. But the real problem is that I don't get what you got.

17000 x .09 x 119 /360 = ?

whoops should it be 505.75 and after rounding it would be 505.80

To find the simple interest, you can use the formula I = Prt, where:

I = simple interest
P = principal amount (initial amount of money)
r = interest rate (expressed as a decimal)
t = time (in years)

In this case, you have:
P = $17,000
r = 9% (which is equivalent to 0.09)
t = 119 days

Since the formula requires time to be in years, you need to convert 119 days into an equivalent fraction of a year.

To do this, divide the number of days (119) by the number of days in a year (360), because the problem specifically mentions assuming a 360-day year.

119 / 360 = 0.33 (approximately)

Now that you have the time in years, you can calculate the simple interest using the formula:

I = 17,000 * 0.09 * 0.33

Calculating this expression, you get:

I = 504.90

Since the question specifies rounding the result, you need to determine the appropriate rounding rule. The problem does not explicitly state how to round, so it's best to follow common rounding practices, which is to round to the nearest hundredth (two decimal places) for money-related calculations.

Therefore, rounding 504.90 to the nearest hundredth gives you:

I = $505.00

Hence, the simple interest would be $505.00.
