Let's use the available discount cards on the items and calculate the final prices along with the grand total. Here’s the step-by-step process for each item:
1. Book:
- Original Price: \[tex]$12
- Card Used: Trebu. (which gives a 12% discount)
- Final Price Calculation:
- Discount: \( 0.12 \times 12 = 1.44 \)
- Final Price: \(\$[/tex]12 - \[tex]$1.44 = \$[/tex]10.56\)
2. Camera:
- Original Price: \[tex]$50
- Card Used: $[/tex]B[tex]$ (Buy one get one free - effective as 50% off)
- Final Price Calculation:
- Discount: \( \frac{50}{2} = 25 \)
- Final Price: \(\$[/tex]50 - \[tex]$25 = \$[/tex]25.00\)
3. Jeans:
- Original Price: \[tex]$24
- Card Used: $[/tex]\omega[tex]$ (which gives a \$[/tex]2 off)
- Final Price Calculation:
- Discount: \[tex]$2
- Final Price: \(\$[/tex]24 - \[tex]$2 = \$[/tex]22\)
Finally, add up the final prices to get the grand total:
- [tex]\( \$10.56 \)[/tex] (Book) + [tex]\( \$25.00 \)[/tex] (Camera) + [tex]\( \$22.00 \)[/tex] (Jeans) = [tex]\( \$57.56 \)[/tex]
So, your completed table and calculations look like this:
[tex]\[
\begin{tabular}{|l|l|l|l|}
\hline \multicolumn{1}{|c|}{ Item } & Original Price & Card & Final Price \\
\hline Book & \$12 & Trebu. & \$10.56 \\
\hline Camera & \$50 & $B$ & \$25.00 \\
\hline Jeans & \$24 & $\omega$ & \$22.00 \\
\hline \multicolumn{3}{|r|}{ \textbf{Grand Total} } & \$57.56 \\
\hline
\end{tabular}
\][/tex]
With these calculations, you can purchase all three items for a total of \[tex]$57.56, well within your \$[/tex]90 budget.
