Question

10.

A
group of friends went to lunch. The bill,/before)
sales tax and tip, was $37.50. A sales tax of 8%
was added. The group then tipped 18% on the
amount after the sales tax was added.
What was
the amount, in dollars, of the sales tax?
What was the total amount the group paid,
including tax and tip?

Answer 1

The total amount of the sales tax: $3.00

The total amount paid: $47.25

Explanation:

Tip (In $): 6.75

Sales tax: 3.00

The total amount of food (before additional fees): 37. 50

So, to find the amount (in dollars) of the sales tax and tip, we must use this formula:

Amount = whole number * part percent/100

So, plugging in the numbers to the formula, it would look like this:

37.50 * 18 / 100
That is how to find the tip, you would do the same to find the sales tax. Then, when you get both amounts, you add them to 37.50 (the total before the fees) and get $47.25.
