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?

A $62.05
B $44.25
C $48.10
D $47.79
Can someone help me again and last question thanks!

37.5 * 1.08 = $40.50 with tax.

40.5 * 1.18 = $_______ with tip

To find the amount of the sales tax, you need to calculate 8% of the original bill amount.

First, calculate the sales tax amount:
Sales tax amount = 8% * $37.50
Sales tax amount = 0.08 * $37.50

Next, calculate the total bill amount after adding the sales tax:
Total bill amount = $37.50 + sales tax amount

Finally, calculate the tip amount on the bill after sales tax:
Tip amount = 18% * total bill amount

Now, let's calculate each step:

1. Sales tax amount:
Sales tax amount = 0.08 * $37.50
Sales tax amount = $3.00

2. Total bill amount after adding the sales tax:
Total bill amount = $37.50 + $3.00
Total bill amount = $40.50

3. Tip amount on the bill after sales tax:
Tip amount = 0.18 * $40.50
Tip amount = $7.29

Therefore, the amount of the sales tax is $3.00.
The correct answer choice is A.

To find the amount of sales tax, we need to first calculate the total bill after the sales tax is added.

Step 1: Calculate the amount of sales tax applied to the bill.
Sales tax = 8% of $37.50
Sales tax = (8 / 100) * $37.50
Sales tax = $3.00

Step 2: Add the sales tax to the bill amount to calculate the total bill after sales tax.
Total bill after sales tax = $37.50 + $3.00
Total bill after sales tax = $40.50

Step 3: Calculate the tip on the total bill after sales tax.
Tip = 18% of $40.50
Tip = (18 / 100) * $40.50
Tip = $7.29

Therefore, the amount of sales tax is $3.00, which is option D.
