Calculate the simple interest and maturity value. (Do not round intermediate calculations. Round your answers to the nearest cent.) Principal Interest rate Time Simple interest Maturity value Principal -$18,000

Interest rate is 7 and 1/4

time is 14 months

what is the Simple interest=

And Maturity value=

Given	Principal: $11,500, 11%, 240 days
	Partial payments:	On 100th day, $4,400
		On 180th day, $2,700

a.	Use the U.S. Rule to solve for total interest cost. (Use 360 days a year. Do not round intermediate calculations. Round your answer to the nearest cent.)
