9(2*2+4➗2)= can you show how to get the answer. which is 54.

Here I'll Simplify it to show the work.
You need PEMDAS

9(2*2+4÷2)
9(4+4÷2)
9(8÷2)
9(4)
9(4) = 9 × 4 = 36

The Answer is 36.

So your saying that the answer is 54. 

Do 4 / 2 first, which you get 2. 
So now we have (2*2+2)
2*2=4, and 4+2=6..
Now we have 9(6), also known as 9 x 6.
9*6=54.

Answer for 2: his profit would be $2.88 explanation: you have to first multiply 72 and 0.12 together to get $8.64 once you do that you know how much money the shopkeeper made from selling the candy bars individually. so you have to do 8.64-5.76=2.88 hope that ; )answer for 3: yeah i’m sorry i have no idea what number 3 is. i’m sorry i couldn’t with that.
