Diane has $60,000 in a savings account that earns 8% annually. the interest is not compounded. how much will she have in 4 months?

Interest = Principle x Rate x Time
Let Interest = I, Principle = $60,000, Rate = 8%, and Time = 4 months
You first need to convert 8% into decimal form: 8% x 100 = .08
Then convert 4 months into years, a year is twelve months, so: 4/12 = 1/3
Then substitute your values:
I = (60,000)(.08)(1/3)
Multiply 60,000 by .08, which equals 4,800:
I = (4,800)(1/3)
Multiple 4,800 by 1/3; 4,800/3 = 1,600:
I = 1,600
However, you’re not done yet, because the question asks, “How much will she have in 4 months?” Which means they want the total of money in her account. To find the total you add the interest with the principle, therefore the total would be: $1,600 + $60,00 = $61,600.
So your final answer is $61,000
