Answer:
$25.65
Step-by-step explanation:
Since we are applying a discount to a price tag, we will be <u>decreasing</u> the amount of that price tag.
In this case, we will be taking 5% off of $27. This means that our new price tag will be 95% of what it originally was. To find the answer, we must first change 95% into a decimal.
95% ->
-> 0.95
Next, we multiple $27 by 0.95 as shown below:

Our answer will be:
$25.65
A:
p = 8n - 30
170.00 = 8n - 30 add 30 to each side
200.00 = 8n divide by 8
25 = n 25 items were bought.
B:
The profite would decrese
8(25) - 40
200 - 40
160 original was 170 but it decreased by 10$
hope this helped :)
