8) Craig borrows $1000 at 9% simple interest per year. When Craig pays the loan back 11 years later, what is the total amount that Craig ends up repaying?=

2) Answer: I = $ 10.56Equation:I = PrtCalculation:First, converting R percent to r a decimalr = R/100 = 0.6%/100 = 0.006 per year,then, solving our equationI = 440 × 0.006 × 4 = 10.56I = $ 10.56The simple interest accumulatedon a principal of $ 440.00at a rate of 0.6% per yearfor 4 years is $ 10.56.4) Answer: I = $ 0.63Equation:I = PrtCalculation:First, converting R percent to r a decimalr = R/100 = 0.7%/100 = 0.007 per year,putting time into years for simplicity,3 months ÷ 12 months/year = 0.25 years,then, solving our equationI = 360 × 0.007 × 0.25 = 0.63I = $ 0.63The simple interest accumulatedon a principal of $ 360.00at a rate of 0.7% per yearfor 0.25 years (3 months) is $ 0.63.8) Answer: I = $ 990.00Equation:I = PrtCalculation:First, converting R percent to r a decimalr = R/100 = 9%/100 = 0.09 per year,then, solving our equationI = 1000 × 0.09 × 11 = 990I = $ 990.00The simple interest accumulatedon a principal of $ 1,000.00at a rate of 9% per yearfor 11 years is $ 990.00.
