Question

Quizplus · Accepted Answer

We can use the formula for simple interest:

Interest = Principal x Rate x Time

Where:
- Interest = $155.25 (given in the problem)
- Rate = 3.5% (given in the problem)
- Time = 1 year (given in the problem)
- Principal = what we need to find

Plugging in the values:

155.25 = Principal x 0.035 x 1

Solving for Principal:

Principal = 155.25 / 0.035
Principal = $4,435.71

Therefore, Tom deposited $4,435.71 in his savings account. However, this is not one of the answer choices. We need to round it to the nearest dollar.

The correct answer is the closest amount to $4,435.71, which is $150.00 (answer choice B).
