Step 1:
Cost price = $139
Discount = 15%
Tax = 6.3%
Shipping = $5.75
Step 2:
Next, find the discount amount.
[tex]\begin{gathered} \text{Discount = 15\% of \$139} \\ \text{ = }\frac{15}{100}\text{ }\times\text{ 139} \\ \text{ = }\frac{2085}{100} \\ \text{ = \$20.85} \end{gathered}[/tex]
Step 3:
Next, find the tax.
[tex]\begin{gathered} \text{Tax = 6.3\% of \$139} \\ \text{ = }\frac{6.3}{100}\text{ }\times\text{ 139} \\ \text{ = }\frac{875.7}{100} \\ \text{ = \$8.757} \end{gathered}[/tex]
Total cost = $139 - $20.85 + $8.757 + $5.75 = $132.657
Final answer
Total cost = $132.657
