Calculate the simple interest and maturity valve for the following problems. Round to the nearest cent as needed. 18,000,4 1/2%,18mo.

18,000 * 0.045 = ?

18,000 * 0.045 * 0.5 = ?

Add the two products together for the total interest.

To calculate the simple interest and maturity value for the given problem, we will use the following formulas:

Simple Interest = (Principal * Rate * Time) / 100
Maturity Value = Principal + Simple Interest

Given information:
Principal (P) = $18,000
Rate (R) = 4 1/2% = 4.5%
Time (T) = 18 months

Step 1: Convert the rate to decimal form
4 1/2% is equivalent to 4.5/100 = 0.045

Step 2: Calculate the Simple Interest
Simple Interest = (P * R * T) / 100
Simple Interest = (18,000 * 0.045 * 18) / 100

Let's calculate the simple interest:
Simple Interest = (18,000 * 0.045 * 18) / 100
Simple Interest = 3,870

So, the simple interest is $3,870.

Step 3: Calculate the Maturity Value
Maturity Value = Principal + Simple Interest
Maturity Value = 18,000 + 3,870

Let's calculate the maturity value:
Maturity Value = 18,000 + 3,870
Maturity Value = 21,870

So, the maturity value is $21,870.

Therefore, the simple interest is $3,870, and the maturity value is $21,870.
