To find the total amount Mohal paid, including sales tax, we need to calculate the total cost of the folders and markers, then apply the sales tax to that total.
-
The cost of the folders, given they are $0.95 each, for \( f \) folders is: \[ 0.95f \]
-
The cost of the markers, given they are $0.55 each, for \( m \) markers is: \[ 0.55m \]
-
The total cost before tax is: \[ 0.95f + 0.55m \]
-
To calculate the total amount including the 3.75% sales tax, we multiply the total cost (before tax) by \( 1 + \text{sales tax rate} \): \[ \text{Total with tax} = (0.95f + 0.55m) \times 1.0375 \]
Therefore, the expression representing the total amount Mohal paid, including tax, is: \[ 1.0375(0.95f + 0.55m) \]
Now looking through the multiple-choice options you've provided, the correct choice is: \[ 0.0375(0.95f + 0.55m) + (0.95f + 0.55m) \] since it simplifies to the same expression as we derived.
However, since this choice isn't specifically expressed, the most straightforward option that captures the total cost and tax together is: \[ 1.0375(0.95f + 0.55m) \]
So your final answer would likely be the 3rd choice provided, assuming it properly expresses the correct multiplication and sum for the total including tax: \[ 1.0375(0.95f + 0.55m) \]
