Answer:
(a)$124.99
(b)$99.99
Step-by-step explanation:
(a)Wholesale cost of the bike = $96.15
Since the store marks up the wholesale cost by 30%.
The amount he will pay for the bike
![\begin{gathered} =130\%\text{ of }$\$96.15$ \\ =(130)/(100)*96.15 \\ =1.3*96.15 \\ =\$124.99 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/o4h8m605lmrqonn0cs68zs9pv3go4e50q3.png)
Andre will pay $124.99 for his bike.
(b)If the bike is then discounted by 20%
![\begin{gathered} \text{Sales Price=}(100-20)/(100)*124.99 \\ =(80)/(100)*124.99 \\ =0.8*124.99 \\ =\$99.99 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/55stsk5xnukk5m639uxnlby0ct2xik15p6.png)
Andre will pay $99.99 before tax.
