Question

The simple interest formula is given by I=Prt, where I=interest, P=principal, r=rate, and t=time. Write a sentence for the formula. Multiple choice question. A) The interest equals the product of the principal, the rate, and the time. B) The interest equals the sum of the principal, the rate, and the time. C) The interest equals the principal times the rate. D) The rate equals the product of the principal, the interest, and the time.

Answer 1

A) The interest equals the product of the principal, the rate, and the time.

Explanation:

Let's see the choice:

• A) The interest equals the product of the principal, the rate, and the time. This is the correct answer. The formula I=Prt states that the interest is equal to the principal times the rate times the time.
• B) The interest equals the sum of the principal, the rate, and the time. This is incorrect. The interest is not equal to the sum of the principal, the rate, and the time. It is equal to the product of these three quantities.
• C) The interest equals the principal times the rate. This is incorrect. The interest is not equal to the principal times the rate. It is equal to the product of the principal, the rate, and the time.
• D) The rate equals the product of the principal, the interest, and the time. This is incorrect. The rate is not equal to the product of the principal, the interest, and the time. It is equal to the interest divided by the principal times the time.

Therefore, the correct answer is A) The interest equals the product of the principal, the rate, and the time.
