I=PRT Let P=2100dollars, R=13%, T = 6 months 6 months =$\frac{6}{12}$year = $\frac{1}{2}$ = 0.5 I = 2100 $\times$13% $\times$ 0.5 Write 13% as a decimal I = 2100$\times$0.13$\times$ 0.5 Multiply I = 136.50 The simple interest is 136.50 dollars. total amount = principal + interest total amount = 2100+136.50 = 2236.50 dollars Total amount after 6 months will be 2236.50 dollars
