Percentages
A
We know that the tax rate is 7.3% and it corresponds to $12.41. We want to find the total price of the table saw without taxes, it is to say the 100%. We have the following equivalence:
100% ⇔ ??
7.3% ⇔ $12.41
If we divide both parts of the equivalence we will have the same result:
[tex]\frac{100}{7.3}=\frac{?\text{?}}{12.41}[/tex]Multiplying both parts of the equation by 12.41:
[tex]\begin{gathered} \frac{100}{7.3}=\frac{?\text{?}}{12.41} \\ \downarrow \\ \frac{100}{7.3}\cdot12.41=?\text{?} \end{gathered}[/tex]Now, we can find the total price of the table saw without taxes:
[tex]\begin{gathered} \frac{100}{7.3}\cdot12.41=170 \\ \text{??}=170 \end{gathered}[/tex]Answer A. the purchase price is 170
B
The total price of the table saw (it is to say, including taxes, $12.41), is
170 + 12.41 = 182.41
Answer B. the total price is 182.41
