To calculate the total cost of the meal including tax, first, you need to calculate the tax amount and then add it to the original meal cost.
-
Calculate the tax amount: \[ \text{Tax} = \text{Meal cost} \times \text{Tax rate} \] \[ \text{Tax} = 47.50 \times 0.065 = 3.0875 \]
-
Add the tax to the meal cost: \[ \text{Total cost} = \text{Meal cost} + \text{Tax} \] \[ \text{Total cost} = 47.50 + 3.0875 = 50.5875 \]
Therefore, the total cost of the meal is $50.59 when rounded to two decimal places.
