12/1 or in simplest form 12. Hope this helps!
Answer:
3/4
Step-by-step explanation:
36/48
Divide the top and bottom by 12
36/12 = 3
48/12 =4
36/48 = 3/4
If you add both 5.75 and 4.75, you'd get 10.5, so your answer is 10 and a half, so D.
Yes you have a good example.
x = number of cookies
2*x = total amount spent on cookies at $2 each
2x-3 = amount you pay after the $3 discount is applied one time for the entire order
-------------
a more numeric example may be this
Lets say you bought 12 cookies, so x = 12
This means it costs 2*x = 2*12 = 24 dollars total if the discount doesnt apply
However, the 3 dollar discount is there, so the grand total is 24-3 = 21 dollars.
You add $5.38 & $15.95, which equals $21.33. Then subtract $21.33 from $38.12. Your answer is $16.79. That's how much Shane spent on the book.
