To find out how much Sam will spend on lunch, we need to calculate the tax and tip amount and add it to the initial cost of $12.
First, let's calculate the tax amount. Tax is usually a percentage of the initial cost. In this case, the tax rate is 7.5%. To find out the tax amount, we can use the formula:
Tax Amount = (Tax Rate / 100) * Initial Cost
Substituting the values, we get:
Tax Amount = (7.5 / 100) * 12
Tax Amount = 0.075 * 12
Tax Amount = 0.90
So, the tax amount is $0.90.
Next, let's calculate the tip amount. The tip is also a percentage of the initial cost. In this case, the tip rate is 15%. Using the same formula as before, we can find the tip amount:
Tip Amount = (Tip Rate / 100) * Initial Cost
Substituting the values, we get:
Tip Amount = (15 / 100) * 12
Tip Amount = 0.15 * 12
Tip Amount = 1.80
So, the tip amount is $1.80.
Now, let's add the initial cost, tax amount, and tip amount to find out how much Sam will spend on lunch:
Total Cost = Initial Cost + Tax Amount + Tip Amount
Total Cost = $12 + $0.90 + $1.80
Total Cost = $14.70
Therefore, Sam will spend $14.70 on lunch.
