Final answer:
Marsha earned $1,425 in simple interest from a $9,500 deposit at a 5% interest rate over 3 years.
Step-by-step explanation:
The student wants to calculate the amount of simple interest earned on a deposit of $9,500 at a simple interest rate of 5% over a period of 3 years. To find the simple interest, we can use the formula:
Simple Interest = Principal × Rate × Time
Where the Principal is $9,500, the Rate is 5% (or 0.05 in decimal form), and the Time is 3 years:
$9,500 × 0.05 × 3 = $1,425
Therefore, Marsha earned $1,425 in interest over the 3-year period.
