First we need to find the sales tax
tax = price * tax rate
tax = 40 * 8%
= 40*.08

Answer: 
Step-by-step explanation:
You have the following information given in the problem:
- The number of soccer fans that are going to a soccer game is 27.
- A ticket to the game costs $18 per person.
- The cost of the lunch for all 27 fans is $172.
-
represents the total cost of attending the game for all 27 fans.
Therefore, keeping the above on mind you can write the following expression that closely estimates the total cost of attending the game for all 27 fans:

X = number of cds on the rack
x + 7 = 30
x = 30 - 7
x = 23 <== so there are currently 23 cds on the rack
-3 so top person is correct:)))))
