Answer:
(a)$124.99
(b)$99.99
Explanation:
(a)Wholesale cost of the bike = $96.15
Since the store marks up the wholesale cost by 30%.
The amount he will pay for the bike
[tex]\begin{gathered} =130\%\text{ of }$\$96.15$ \\ =\frac{130}{100}\times96.15 \\ =1.3\times96.15 \\ =\$124.99 \end{gathered}[/tex]Andre will pay $124.99 for his bike.
(b)If the bike is then discounted by 20%
[tex]\begin{gathered} \text{Sales Price=}\frac{100-20}{100}\times124.99 \\ =\frac{80}{100}\times124.99 \\ =0.8\times124.99 \\ =\$99.99 \end{gathered}[/tex]Andre will pay $99.99 before tax.
