The interest accrued on $6,400 at 6% for 75 days is: (Use 360 days a year.)Multiple Choice$448.$45.$38.$192.$80.

To calculate the interest accrued on a sum of money, you can use the formula for simple interest which is I = PRT, where:

• I is the interest
• P is the principal amount (the initial amount of money)
• R is the rate of interest per period
• T is the time the money is invested for

Given in the problem, we have:

• P = $6,400
• R = 6% or 0.06 (you need to convert the percentage into a decimal)
• T = 75/360 years (since we're using a 360-day year and the money is invested for 75 days)

Now, plug these values into the formula:

I = PRT I = $6,400 * 0.06 * (75/360)

Calculate the above expression to find the interest. The correct answer will be the one that matches this calculation.
