Step 1:
Calculate the discount price
The discount rate given is
![=15\%](https://img.qammunity.org/2023/formulas/mathematics/college/h5ps0jh4qc5qeamok8m5y3shf7pi0fhl29.png)
The discounted price will be
![\begin{gathered} =(15)/(100)*\text{ \$63} \\ =(945)/(100) \\ =\text{ \$9.45} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/eiac1b70og6v926pxj3xlb514rkagw8fv5.png)
Step 2:
Calculate the selling price, we will have
![\begin{gathered} \text{Selling price=original price - discount} \\ \text{Selling price}=63-9.45 \\ \text{Selling price}=53.55 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/3cuwio0onafwsmi1a2sh2ab6aez5wmca4b.png)
Hence,
The sale price of the sweater will be = $ 53.55
