To find the total amount Alejandro paid, including sales tax, we start by determining the cost of the folders and markers:
- Cost of folders: \(0.20f\) (where \(f\) is the number of folders)
- Cost of markers: \(0.55m\) (where \(m\) is the number of markers)
The total cost before tax is given by the expression:
\[
0.20f + 0.55m
\]
Next, we add the sales tax of 8%. The total cost after tax is calculated as follows:
\[
\text{Total cost after tax} = (\text{Total cost before tax}) + \text{Sales tax}
\]
\[
= (0.20f + 0.55m) + 0.08(0.20f + 0.55m)
\]
\[
= (0.20f + 0.55m)(1 + 0.08)
\]
Thus, the expression that represents the total amount Alejandro paid, including tax, is:
\[
(0.20f + 0.55m) + 0.08(0.20f + 0.55m)
\]
Looking at the provided multiple-choice answers, the correct one is:
\[
(0.2f + 0.55m) + 0.08(0.2f + 0.55m)
\]
