Answer:
A. Supplier X offers the better deal by $3.93.
Explanation:
Supplier X offers a mechanic a part at 35% off the retail price of $65.40.
[tex]\begin{gathered} Supplier\text{ X's price}=65.40-(35\%\text{ of \$65.40\rparen} \\ =65.40-22.89 \\ =\$42.51 \end{gathered}[/tex]Supplier X's price is $42.51.
Supplier Y offers him the same part at 20% over the wholesale cost of $38.70.
[tex]\begin{gathered} Supplier\;Y^{\prime}s\text{ price}=38.70+(20\%\text{ of 38.70\rparen} \\ =38.70+7.74 \\ =46.44 \end{gathered}[/tex]We calculate the difference in the prices below:
[tex]46.44-42.51=\$3.93[/tex]Supplier X offers the better deal by $3.93.
