Answer: the interest owed is $21

Step-by-step explanation:

The question is incomplete. The complete question is:

Sari Tagore obtains a $1000 loan to purchase a laser printer. Her interest rate is 7% ordinary interest for 108 days. What is the interest owed?

Solution:

When calculating ordinary interest, we assume that a year has 360 days. We would apply the formula for determining simple interest which is expressed as

I = PRT/100

Where

I represents interest paid on the loan

P represents principal or amount borrowed.

R represents interest rate

T represents duration in years

From the information given,

P = 1000

R = 7%

T = 108 days. Converting to years, it becomes 108/360

Therefore

I = (1000 * 7 * 108/360) / 100

I = $21
