find the interest. round to the nearest cent $290 at 8.8% for 3 months

6.38

I = PRT

I = 290 * 0.088 * 0.25

I = ?

To calculate the interest, you can use the formula:

Interest = Principal * Rate * Time

Where:
Principal = $290
Rate = 8.8% (which is equal to 0.088 in decimal form)
Time = 3 months

Plugging in the values, we have:

Interest = $290 * 0.088 * 3

Calculating this expression, we get:

Interest = $76.968

Rounding this to the nearest cent, the interest is $76.97.

To find the interest on a loan or investment, you can use the formula:

Interest = Principal x Rate x Time

In this case, the principal (P) is $290, the interest rate (R) is 8.8% (which needs to be converted to a decimal), and the time (T) is 3 months.

First, convert the interest rate from a percentage to a decimal by dividing it by 100:
8.8% / 100 = 0.088

Now, we can calculate the interest using the formula:

Interest = $290 x 0.088 x 3 months

Interest = $290 x 0.264

Interest = $76.56

Rounding to the nearest cent, the interest is approximately $76.56.
