To calculate the total interest to be paid, we can use the formula for simple interest:<br /><br />\[ \text{Simple Interest} = \frac{P \times R \times T}{100} \]<br /><br />Where:<br />- \( P \) is the principal amount (the amount borrowed)<br />- \( R \) is the annual interest rate<br />- \( T \) is the time in years<br /><br />Given:<br />- \( P = \$12,000 \)<br />- \( R = 8\% \)<br />- \( T = 3 \) years<br /><br />Substituting the values into the formula:<br /><br />\[ \text{Simple Interest} = \frac{12000 \times 8 \times 3}{100} = \frac{28800}{100} = \$2880 \]<br /><br />So, the total interest to be paid is $\$2,880$.<br /><br />For the second question, to calculate the sale price of the jacket after the discount, we can use the formula:<br /><br />\[ \text{Sale Price} = \text{Original Price} \times (1 - \text{Discount Percentage}) \]<br /><br />Given:<br />- Original Price = $\$200$<br />- Discount Percentage = $15\%$<br /><br />Substituting the values into the formula:<br /><br />\[ \text{Sale Price} = 200 \times (1 - 0.15) = 200 \times 0.85 = \$170 \]<br /><br />So, the sale price of the jacket after the discount is $\$170$.
